How to stop ppl not from your friends list inviting you to random chats?

Block all of the modders of the group/ignore the requests.

Got it too 1 hour ago...

Can't view his profile from in chat?

On the steam chat, next to his name, should be a tiny arrow, click on it and a drop down menu should appear. There should be an option called block all communication. Click on it and follow through and the player should be blocked from communicating you. Hopefully this helps :)

The group got whacked, and I hope the creator is too.

I have the same problem. Its no one that I'm friends with, and it doesn't identify any group that I'm part of. And I don't think I've ever seen the same person or title twice.

I've found the user that's sending me group chat invitations in one of groups I'm member of. That might be the reason why I got few phish friend invites, too. Oh well.

Same here, it's terribly annoying...

Seems like one douche has been inviting us all lately, what a jerkwad.

So I'm not the only one getting this invitations. Anybody knows where is this guy finding everybody?

Easiest way to avoid annoying invites and event notices, is to turn chat to offline. Just the chat, everything else about Steam still in online mode.

A new generation of phishing / scamming has BEGUN! Anyway just report the group and the inviter like you'd do with link scammers.

1) Receive random friend invite from stranger.
2) Check to see if said stranger left an explanation on my Steam wall.
3) Click on "Ignore" when there turns out to be nothing written on my Steam wall.

I got the same thing a few days ago. The problem was it was multiple different people inviting me so even if I did block them another person would just invite me instead. It is very annoying but it seemed to stop the next day and I havn't seen it since. So I guess just put up with it for a little bit and it will stop.

just block them, or go offline.
