more "excluded" keywords in "comment automation"

Hi, could you allow more "keywords" in the "exclude" section in comments automation? That's really nice automation, but rude IG users are abusing this so much by asking inappropriate questions. Let say we have a keyword for "how much" (it's very common question), so people started to abuse it by asking for "how much" is a slave, cocaine, unborn child, your mother etc - their creativity is endless, but "excluded keywords" limited to just a few words. Our reply, "Sent DM!" looks even more inappropriate. In order to use that automation, we need much more keywords to be excluded. Thanks!
