My old Reddit account gets regularly scrubbed because Reddit keeps restoring shit. First, all posts get deleted (again), then all comments get replaced with crap, and after a few months, they too get deleted.
A mod looked at my profile and couldn’t wrap his little brain around it. Hundreds of thousands of comments and post karma, but no posts. How? LOL
Tbf, bot accounts also do this. They copy-paste other user’s hightly voted comments to gain karma, then delete their history, then use the account for agendaposting.
Yeah, before I left Reddit, every day you’d see a thread that was previously posted a few months ago, with the top comments then reposted. By just duplicating a post on one bot account, and then the top comments on other bot accounts, the bot farms can build up many accounts very efficiently.
