Substring search has been replaced with an advanced regex. It should catch most bypassing-attempts, but it will also take care of ignoring words like "multiple", "stipulation" and whatever else crazy words you come up with.

P.S.: Just because some ways of bypassing are now impossible by default, this doesn't entitle you to "test" ways to bypass it in a public raffle just to avoid a ban. You've been warned. We will get enough data for improvements on the detection by legitimate rule-breakers soon enough, so no need for your "help". But thanks anyways.

In case you are worried about "but now I cant ask for advice on TF2 gaming or how to get this and that"...
..well this is a stupid excuse for a change you dislike. There are dozens of synonyms for this word that triggers "the button" to be hidden. You know, like "suggestions", "advice", "help".... that's just a few!
