might be true, this user reset its password recently, someone please neg rate this user

Need more proof than just a baseless allegation. He needs to prove the account was his before someone negbombs it.

if this is hacked account then original owner should post a signed message from old btc address he posted in an unedited post

IS this helpful ?

yes its enough
just start a new thread in scam section with those message and proofs
i hope someone from staff or admin will help you about this
