It's a
cruel hilarious joke that theymos plays on people who get banned: it gives you the illusion you can somehow be the exception among the rest of the rabble that get banned for plagiarism on a daily basis, just like the "close doors" button in an elevator or the "push to cross" button at a stoplight.
But I see no reason for a permanent ban, there must be a way to restore the profile.
It's amazing how similar these threads appealing a ban for plagiarism tend to be. The OP professes ignorance of what he's done; other users dig up examples of plagiarism; OP claims this isn't a big deal and ought to be given a second chance; users laugh as they relish the delicious schadenfreude; OP either leaves in disgust or starts calling us
"dog" [sic] (and then leaves in disgust).
