I’m not sure if this is possible already, but here goes:
We’ve been getting spammed constantly with the same exact URL (the one shown in the screenshot below). It’s annoying, and it seems like we could add this URL into a complete blacklist, where the user is blocked instantly from creating any new posts, and the post is never seen by anybody (except moderators).
This kind of feature always leads to false positives… but in this case, I can’t imagine it would. Could also restrict it to just users with under 10 posts, or something like that.
