You're welcome to0da

Alright, I didn't have any trouble joining other servers (seems like it was on TF2) but thanks anyway, I will avoid these servers now

Hey tehre To0a, they are on all of the below:
Half-Life 2 Deathmatch
Black Mesa
Day Of Defeat
Counter-Strike-Source
Team fortress 2
Left 4 Dead
Left 4 Dead 2
Counter-Strike Global Offensive
Insurgency
Day of Infamy
Fistful of Frags
Pirates, Vikings, and Knights 2

I just saw you were connected on their address so I wanted to warn you about it.

What game are we even talking about?

Hey To0a, I wanted to warn you about the server you were connected to. It is called Fastpath.
They have stolen your steam auth ticket because you still appear to play there.
They are scammers and create about 80+ fake servers on the many games.

You might have noticed many server you click on redirect you there?

They steal server + player names - making it hard for anyone to find a real server.
They also steal your Steam Auth ticket for up to 5 days.
The way to revoke it is to connect to a legitimate server. < IMPORTANT
They ban and then request money for unbanning players.
They publish players real identities.

You can also see the discussions about this issue on this link for example:

If you like you can download the blacklist so all these fake servers are hidden from your list:
