I think this is an attempt to steal your Steam account. Beware.I got a message today from someone named Snake (No not our Snake) anyway it was a request to join some group. I decided to go ahead and look at it but I copied and pasted the web address into a browser instead of clicking on it. The first thing that comes up is a web page that looks a lot like Steam and is asking you to sign in.
The next thing I did was go and try to open it through steam and Steam tells me it is not an official webpage. So I think this is an attempt to steal your Steam account. Beware.
Here is the web address given.
