Is it okay to ask here if a site is legit or scam?

Sure but know this: insert any csgo gambling site here is a scam.

I'm talking about a specific csgo gambling site.

Yep, that's a scam alright. Don't even need to know the URL for that.

You can put the name of the site in your OP, remove any referral it might have as guideline of SG doesn't allow it =

• Referral links are not allowed in the community, and if you choose to post a link, please be sure all referral codes have been removed (http://www.example.com?ref=12345 to http://www.example.com).

It doesn't "smell right" when you say

"asked to join.. and pass me some in game gold and buy something for him"

But it wouldn't automatically make it a scam.

No, just no. Don't do it.

This thread is much better than reading one tomorrow about how you were scammed.

thanks to you all guys for the heads up, I'm closing this thread now, you all are right. Cheers.
