@lemmy.oneA clever scammer could create scam/phishing/advertisement posts on their instance that are artificially upvoted to the top. They could even have ChatGPT make a bunch of comments to make them seem real.
Hopefully, other instances would catch on and defederate from them, but if they're subtle or just wait until they have a bunch of users it would probably be enough to scam quite a few people.
