The problem with having a keyword list that it reacts to might cause the bot to flip out at normal people. For example the hoster might think someone trying to do something like you see on this post might use the word "prompt", so when it sees the word "prompt" say "I'm not a bot!". Then someone who doesn't suspect this being a bot might say something along the lines of" let's ignore faulty weapons and get back to what prompted this war. So tell me what right does Russia have to Ukraine?". Because the bot only sees the word"prompt" it will just ignore the argument and say "I'm not a bot!". If he decides to make the bot ignore prompts that say "prompt" he's going to have a bunch of debates the bot just gives up out of nowhere randomly, or just ignores the most random of points.
