To verify Ratimov's plagiarism claim, I checked
the unedited post, and unlike someone who would post a small link at the end of his long copied topic, NotATether started his topic by giving credit.
According to Ratimov's own "if it doesn't break the rules then it's fine even if it's unethical" approach, it'd be perfectly fine to not have a reference at all. Since the original thread doesn't exist, NotATether
probably wouldn't get banned for plagiarism. Except sane users like NotATether aren't hell bent on bending the rules.
I know I shouldn't be surprised at the depths of petulance Ratimov can sink to... but I'm still surprised.
