I remember some malicious software is spammed by multiple users which mods probably have this kind of bot or keyword detection, if i remember correctly, mprep have it.
That's why I thought a restriction or something could help reduce that spam.
The only downside for this is some of the innocent users like replying/quoting or making report post will get affected. But if this can be enabled and disabled like if there are many reports that has the same contents, then it could be enabled to auto-delete once post with such keywords detected.
