A feature for Discord to auto ban accounts that spam @mentions

So, recently. The Android Discord server has been getting raided a lot. And I mean A LOT. So, how about Discord makes a feature that auto bans people who send a message that contains 4 or more @mentions. If they were legit messages and not intended to be a raid, then they can appeal by either emailing support, or something else. But I'm getting tired of these raids.
