most likely the @crzy account is indeed an alternative to the banned account. but the proof of transaction that you provide will not be enough to penalize the @crzy account.
It seems that the Mod is also more careful in handling cases of account ban reports compared to cases of plagiarism.
So you have to provide data matching from the banned account with the active account. and of course, the post is still on the forums. it hasn't been removed by the user, as @Xal0lex said.
Based on their own experience, global moderators do not consider links to posts from Ninjastic.space, as well as Loyce.club, as evidence. Posts that are used as evidence of any violation of the rules by users should be on the forum on a mandatory basis.
