E.g:-
My steam link:-
http://steamproxy.net/id/DangerousCaptain

scammers will use it as:-
http://steamcommunitty.com/id/DangerousCaptain
or
http://steamcommuity.com/id/DangerousCaptain
or
http://steamcommuniity.com/id/DangerousCaptain ETC ETC
if you click on it your account will be long gone!
hijacked...

Real spelling is:-
http://steamproxy.net
but they will provide a change link "thesteamcmmunity" Etc
so before clicking on any link check out for the spelling's..
you would even check it in groups chat,discussions etc.
Thank you
