I no longer feel safe on Steam.

I am a trader. Stop posting comments isn't a workaround for me.
I constantly am offering TF2 Keys for other steam gifts.
This is pretty much how trading works and I don't see how it possibly could lead to community ban.
I'd really appreciate to hear some thoughts on this.

I think you should ask people to PM you first, openly asking for items might come across as "scammy" and I assume someone reported you as such?

comments are also a goldmine for bots that will add you to send fishy links, don't comment

Steam support is trying to prevent people from abusing regional prices (and that's kinda understandable), that's why trading gifts for <you name it> can be considered bad behavior. Of course, if you ask me, they gone too far with their efforts - it's not like people can create steam gifts anymore, so now gifts is more collectible items than just games, especially in case of those "Unknown package" gifts. They clearly got triggered because you used the word "purchase" instead of "trade", but honestly, that's very poor excuse for such an extreme action as community ban (or any at all, tbh).
In my opinion you did not violate anything in steam ToS, at least by it's word. But clearly steam support don't care. Same as my VAC ban has nothing to do with cheats, but hey, their software were triggered by something, so they don't care about the rest, should have known better than leaving CSGO in background.
And no, steam support is not negotiable, they won't give you a benefit of a doubt, if they can't give valid reasons - they will just close support ticket and ignore you. It is how it is.

Well steam is just being steam. There is no way they will say sorry because they are wrong. I lost hope in their support long ago - most of them are also plagued with bots or human with copy paste answer btw. It just aint worth it.

Steam support is quite bad. I tried for around a week to use PaySafeCard to fill my wallet. I select the payment method and click continue. All I get is a message saying that there was an unknown error and transaction couldn't be completed. I'm not asked for a code or anything, I don't get there. Messages back and forth with support and they tell me to contact PSC about my account (wtf?) and regardless of how I explain what's going on and how they're not helping at all, all I get is boilerplate answers, finishing with a "we gave you all the info needed, bye" message and closing the ticket.

So probably no conscious being actually read anything of your ticket, you got banned because someone reported you, and support didn't care about anything once they lifted the ban, so you received boilerplate answers. Probably, but it's just my opinion based on my experience and others' comments on theirs. If they made a mistake, they're not going to admit it.

It looks as the end of your trader career on steam. At least with that account.

If it is or isn't against the steam TOS.
I am sure you can't force them to change their decission and i am sure you will not hire a lawyer to try it that way. And steam know this too.

End of the story.

Don't get me wrong, i don't know you, so my words aren't something against you but trading, normaly done in a way that steam don't earn their market share, isn't liked from steam (and i understand why).

Mentioning the monetary value of the keys could have triggered some anti scam protocol as well, along with other ideas posted above by others like using the word "purchase" instead of "trade". Yeah, the key dealing community may commonly use one terminology, but corporate Valve / Steam can only allow these to be referred to as trades since purchases get tied up into tax laws.

Seems like making this kind of offers on random ppl profiles make them feel less safe on steam.

I personally don't see the problem with what you wrote, but it's safe to say that the best way to trade is directly through DM's. They should have an implementation where you can do the trade offer via Steam interface. They could from there accept it or reject it. It would be a safer approach and feel less scammy if it's a Steam integration.

I can't help but not to point out how cool it is to own these games and share them as a display. I know it's not related to the subject, but it's something I wanted to share. I've been trying to get Ultimate Alliance 1 & 2, but can't buy them anymore, and on grey market, it's extremely expensive. I would have also loved to own Deadpool.

Yeah, I think I'll play it safe from now on. send a friend request, wait, dm my offer.
That way it's safer. However, less efficient than my usual method of stating my offer (you know stating prices is more eye-catching).
I guess I'll go with the safer way from now on.

awwww thank youu, i'm glad you like my showcase 🤍
you've got quite awesome showcases yourself :3

Sorry to hear that, I also don't think you did anything wrong but indeed it is better to play "safe".
I only have one experience with Steam support and it was surprisingly pleasant. I used to trade in the past, I made this trade with a person, where I gave cs:go keys and they gave me a game, similar to your case, around 40$ offer. I activated the game and started playing. Shortly after, the game got deleted from my account indicating it was purchased via credit card fraud. I didn't get any ban but the game is gone and my keys are gone. I contacted the support and mentioned how I got the game and that they can see the trade history etc.
They reverted the trade and gave me my keys back. I was very surprised and happy. This was around 9 years ago though.

I think you got community ban for spamming. Screenshots comment section is not for trade discussions and anyone who comments my screenshot is most likely to be reported fro spamming. Coldplug have most probably reported you for spamming his team Fortress 2 screenshot.

Not for nothing but if the possibility of getting a community ban is what makes you feel "unsafe' someplace, you have been living a cushy life.

Someone reported you for spam. Something about your posting style or habits made them think you were a scammer. Or your competition tried to have you removed. There's nothing to feel unsafe about. You were banned improperly. You appealed. The appealed went through. No company is going to explain the ban process to you. No company is going to explain their moderation process to you. Any explanation opens them up to further arguments and possibly even lawsuits. They will always keep it secret.

You got your account back. Move on with your life. End.

Great work from Steam support keeping the community safe from malicious spammers.

This wasn't smart because scammers have been posting in users screenshot section for awhile now to try to add them as friends so they can scam/phish them. They've done it to me so I would have been very suspicious too.

A person's screenshot section is not the appropriate place to request a trade. Send a friend invite and leave a comment on their profile. If their profile comments are disabled then just add them and hope they accept. If they don't then move on.

You could communicate through trade sites like Steamtrades and Barter first instead directly on Steam. I agree on trade with people on these sites first and then do the trade on Steam. Never had a problem so far.

i never felt safe period.

btw for the people that are talking about scamming, youre saying this on a steamgifts and steamtrades website.

If you want to trade, look for people on Steamtrades.com , barter.vg , or indiegameswap on Reddit that are looking for trades and make them an offer on those sites. Don't just randomly post comments on peoples profiles asking to trade.

Steam is just being Steam ! its overkills on stuff everything, im happy you got your account back to normal :) Also you might try using a spare account for trade purposes.even something happens to it , your main account is safe !
