Special:Badtitle/NS90:Forum:Wiki Talk/Suggesation: global typo substitution/reply (9)

I don't think the examples above have legitimate uses (except on lampshadings, such as Villian the Villian, and on pages about errors, and in "vaudevillian"). So you won't be "fixing" any legitimate uses. If someone types "villian" when they mean "vanilla", your bot would replace the error with another error, but you haven't increased the number of errors since it was an error anyway, and you would have genuinely fixed hundreds of errors in the meantime.

Also, there's no need to ignore uppercase examples. What if the bad spelling starts a sentence? (You won't catch Villian the Villain because 1) it's on a page about errors, which you should skip anyway, and 2) I stuck a comment in the middle, so the bot shouldn't find it.)
