I'll take a crack at it.
Where are you looking to place the tipper?
Does anyone know of a moderation plugin/bot(or even a feature built into NodeBB natively) that can automatically remove new posts based on words or links that are most likely spam?
I know of several subreddits that have this functionality built into them, so it seems like there should be a way to do this within a NodeBB forum.
For instance, if someone tries to post anything with the word "Lucifer" in the forum (either as a new topic or in response to an existing topic), the post will never even be seen by the public because this bot should automatically remove it.
Is there such a thing?
