I’ve heard of vigilante groups doing it for content. There was a case I remember from last year where a man was attacked - the person he was talking to never claimed to be underage, but was a group of people trying to make something for a YouTube channel or something. Didn’t find the article, but the search terms “innocent” “pedobait” and “vigilante” provide enough search results to suggest that it might be a problem.

In Russia, Ghana, and undoubtedly other countries but those are ones I’ve read specific examples of recently - it’s not uncommon for gaybashers to get on apps like Grindr and get entirely away with it. Likely that one of the strats is to claim to be pedobaiting.
