It was honestly very obvious, I knew a google search would spit out an exact copy. As Jerry inadvertently noted, it read just like news written by a copy editor or program.
Cheetah is a bot doing great work on this front, you might want to check the project out. Detects plagiarized original posts (maybe not comments), then pastes a comment with link to original in a non-confrontational manner.
Yeah, I know and love that bot, but can't help with comments. There's never a blanket solution for these things.
