What are the ways that a gift can work on Steam?

pretty sure it's a scam based on the link "snteamcommunity"
scammers do this intentionally to make it look like the link is legit

if it doesn't show up in steams notifications(well.. outside of chat messages) ignore it, those are links that can get your account compromised, the one sending you the link had their account compromised(unlikely to be an impersonator... but if you don't interact with them might as well unfriend)

When you cashed in on the totally legit 50$ offer I have another 20$ for you.

If you have more time to spare I know a Nigerian prince who desperately seeks someone to help him with his financial transactions.

Sounds like an obvious scam to me. If someone you don't really know but who is a part of your friends list was to send you a gift out of the blue, I'm pretty sure they would be messaging you something more personal before even sending you a supposed link for cash or a game of that worth.

The fact this person has a SG account and is in good standing doesn't mean anything. Their account probably got hacked and stolen using the same technique.

It's usually frowned upon to "call out" people on SG but can you post who you're talking about in the OP just so people can know that person's account was hacked and is not behaving as it should?

I was fine without the 50$ coupon, so if I feel it to be suspicious, I can just refuse it.
Most of these shenanigans are scams. Even if they are honest, at the end of the day, it's better to be "without having gifted a $50 coupon" and keeping then money you already had, than be scammed out of a lot more of it on a longer timeframde.

wrong link = instant block. it's really as simple as that. not like anyone is typing it out symbol by symbol to make a typo, so it's a phishing attempt (and not a very clever one)

don't even bother lol

You know people can be also "hacked"? (maybe that person clicked on this link and now they are hacked, it automatically sent this message to you too)

Someone is also tried to hand over all his assets to me because he's dying of cancer but he needed 500$ for paper work. I mean why these scammers think people are fools?. I told him to donate everything then he never replied.

I am sure you speak about LegendaryEagleKnight, the owner of the group Knights Of Havenshire.

If so, i already answered someone else to the same question.

That account got hijacked because he typed his login name and password into a phishing, = fake, steam login page.
Most likely because he wanted the $50 and switched the brain off as soon as he seen the $$$ sign.
Report his account to steam as hijacked, this way the owner get it faster back and the damage that can be done from the intruder in his account are minimized.

Each link that offer $, in whatever way, and aren't written correctly are ALWAYS a phishing try.

Always login to your account with steam shop sites, as example: https://store.steampowered.com/app/858710
This way it is safe.
When you are logged in and a other site show a login page where they want the name + password, you know that this are always a fake (phishing) site. Because real sites would only show a green login button (because you are already logged in on steam and the extern site only need the "yes, it's true" info from steam).

People talk often from "hacking" but it isn't hacking.
The people are only absolute dumb that give the intruders their login and password, on the silver plate, as soon as the greed kicks in and $$$ are offered.

It isn't a good sign if a group owner fall for such stuff and should bring up some security/safety thoughts.
(The damage can be much higher as only the damage for his own account)

curiosity is what gets people to fall for these scams. ive read there are sites where you can make whatever URL you want, similar to the original as can be but really its a redirect to their site which cause force an install or cookie, etc etc, you wouldnt even need to type your login and password, it just takes it. anyway, thats what ive read before somewhere, im no expert but yeah, if they sent you a gift youd get a notification on steam, not a message from the person saying hey buddy click this

Account might have been hacked

Never click links that have come from random people and random places
