It was no late that I was informed by my friend that my account got red trust for cheating campaign with alts.
Here what I found -


Someone used my username and applied in the campaign.
I have no knowledge about the owner of the account, nor I had any previous chat with him.
I am ready to give every possible test to determine that I am not attached with this account.
Site admins can check IPs of both account or anyone can track posting habits or blockchain.
Any thoughts on how can I get rid of this trouble. If done intentionally then it is very harmful for forum.
