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.
I think he probably meant report one of the posts with a message to the mods to check the user's profile for other instances of plagiarism, although that's not the right way to go about it--or it could just be a misunderstanding due to language. Either way, if the member in question hasn't been banned within maybe a month I'd probably report those posts again. I don't think this is a case where "leniency" should come into play.
@iroh, don't waste your energy here, probably he has the big Boss in his corner.
If you're referring to Theymos there, I seriously doubt it. The only member who might have Theymos in his corner is Coolcryptovator, or Cryptovator, or whatever his name got changed to. Twice. Sorry, I'm not bitter about being refused a change of username. Not at all, not one bit.
