Ps. Mods doesn't choose who to ban or not.

Report the Profile to the mods again and wait for the result.
Report profile? So what does that have to do with plagiarism, you are not reporting a profile, but some kind of content that has to do with that profile. Given that the posts in question have been deleted, the only thing someone can do now is to find new plagiarized posts (if they exist) and then make a report.
