@rimu @Andres Not related to bad behavior, but Phanpy displays a ratio of interaction types on the profile page. See “Last 20 posts in the past X days” section. You have to click it to see the ratio tho. Might spark some ideas.
Also, this is sounding a bit like Spoutible’s Bot Sentinel rating. An algorithm decides if you’re good/bad and assigns a letter grade. Users can decide to hide or limit others with a low letter grade.
