A long, long time ago (early 2000s), there was a plugin/add-on/whatever for MS outlook, I think, that would analyze what you wrote and assign it a score from 1 to 3 chili peppers. The angriest, hottest stuff could be prevented from being sent. It was designed as a way to prevent you from sending an email in haste that you might later regret. GmailLabs had something similar with their email goggles function, that could require you to solve math functions before sending email late at night.* While those were cutesy examples, this is in the same vein. If you're worried about the sort of thing chilis/GmailGoggles/Alex would catch, then you're probably happy to run a check like that. If not, then don't. *Gmail Goggles, while a cool feature, didn't really work for the mathematical-minded. Turns out trying to multiply 3-digit numbers while drunk is kind of fun.
