I'd just have to write a side-script to prevent users from just wrapping their messages in ["quote"] tags.
Quoted text isn't counted for payment for signature spammers, so they're unlikely to hide their plagiarism that way.
Never knew that. But I cant see why some one would copy-paste. Good to know its checked. At first glance BTT looks complicated for me. But I now understand the complicated for a lot of reasons.
Copy/pasting is rampant on this forum. For bounty sig scammers it's the easiest way to get a high post count in a quick amount of time while looking like you're spending the time to write out a post.
Because most campaign managers have to manage many participants, plagiarism (copy/pasting) can get overlooked.
TBH, by building these scripts, campaign managers should have an easier time (in theory).
