Invalid marked for no reason

i have been marked as a scammer here from reddit for no proper reason...
i posted a comment on reddit which was suppose to be a joke and suddenly i see that i have been marked as a scammer...
it was a joke posted by me saying that i scammed a scammer but i posted that i traded an osky which is a courier is dota 2 for another courier called garran in dota 2... in reality i traded my osky+ battlefury which is inscribed for that garran which is suppose to be a fair deal but i made a stupid comment which was suppose to be a joke but i was banned....
im pissed because there is no proof that i scammed any1 and to be honest i never did...
this is so frustrating for me since i have been a trader for more than a year and this is the first time the community has created a problem....
im looking for some1 to help me out or who can talk to me about this...
Please do reply..
thankying you in advance...
