I can recall several instances over the past couple of years, of games being played with keywords. Some appeared intended to harass a particular poster, some were meant to discredit a particular author, topic or political figure, and some were added by the person who posted the article, in an effort to gain sympathy ... playing a sort of "keyword victim." Not only do the mods know who added the keywords, they are able to identify them by IP address, if need be.
Keyword usage has changed a lot lately. There was a time you could add an unlimited amount, and that got abused.
I’m glad I am not a mod here. It must be tough and frustrating.
