your Account (i assume it's trampek) is not banned.
If you see a message regarding not being allowed to log in with your machine then that machine was used with a different acc in the past (and neither that nor your acc are linked to steam)
to fix this you will have to link your acc to steam
tnx it wasnt smurf account - just that day when that 1 account/comp rule was added i was logged on my work comp with this account so had to create new at home , i dont think i ever used this old account until now cos didnt got time at work anyway
thats how it was ... and if making new account then playing it for like 700games and only it - is smurfing then tbh i dont know what smurf really mean tnx again for fixing it tho , dont wanna argue as im happy i can play again whichever account
