People fail to realise that reputation is everything. Hive has one thing: cheats remains cheats when they're caught and that blot or tags never really leaves them for the period of time they're around. One reason I support this is, no plagiarist is ever sorry until they're caught. More like medicine after death.
That is the thing. They are only sorry they got caught, not that they did what they did. It is intentional deception.
It's of course a different thing when they don't know that the standard of the chain is not accepting plagiarism. Often popular with recent users I guess.
