I've noticed an uptick of necroposting by what look like bot accounts. They follow this pattern:
1) Create account in the early morning hours: 2-4 am ET
2) Dig up a topic a more than 6 months old
3) Post a reply that could be chat GPT created (they seem to be quite generic, like a post on how to find used furniture being revived with a generic reply to check marketplace or used furniture stores
4) The above all seem to be performed in less than a minute of Total Time Spent Online
I don't know what the overall goal is - just to establish accounts with a posting history for future use maybe?
Our helpful forum members start engaging with the original post, unaware that the topic is old, and the user who originally posted has already bought the car/couch/table or decided not to. If I as a normal user reply to an old post, I get a warning that it's old. But there is nothing to indicate on the main community page, default sorted by "last post" to suggest I'm reading something revived by a bot. Could I suggest one of these:
1) limit the ability of brand new accounts to necropost
2) Don't allow posts by accounts less than X days old, or with less than X posts to affect a thread's chronological position if they do post (to prevent them showing up on the first page)
2) Display necroposted threads with "-revived 3/18/25" letting users know it's a revived subject - this would prompt real users to read the very most recent post and see if they want to interact with *that* post instead of a normal user's propensity to start from the beginning of a thread.
