thanks

I was playing normally in May and my pc broke. Then when i was to my account maeby like July-August i saw like 30 notifications on comments. I went to check them and I was banned from the Trading Card Forums. Then i checked my profile and i got like 15 comments that sayed +rep even tho i havent traded because my pc broke. I couldnt join some trading servers and i was curious why i was banned from servers i havent played. Then i went to check my rep profile. IT SAYED SCAMMER AND THAT I HAD FAKE REP. i saw some items missing. My friends had deleted me from their friends list and someone had changed my description by couple of letters. So i was hacked. Now i cant go to outpost or anything. So plz tell me how can i get this stupid ban away. thnx
