These persons got hacked by a steam based virus!!
The virus is masking it self as an link above!
Just to tell you that their usernames HAVE been different!
This is a warning to all of you!
So whatever this virus does. Apparently it steals all your items in your steam inventory and hacks your account to spread this virus to all of your friends!
So don't click ANY of these links even if they are from your best friend!
Otherwise make sure there is an actual person sitting there before clicking.
Stay safe out there and spread the word!
