Lemmy seems to be overrun by post and ditch throwaway accounts right now posting controversial or divisive content. Because these accounts are created, post, and self delete their accounts and repeat you can't simply just block these users. This is happening on multiple instances and communities too so you also can't just filter out the offending instance.
Please add a filter for content posted by new accounts. Lemmy already has a New Account Highlightenator feature, which is helpful (tho sometimes the baby face tag gets pushed off screen if the username is long when Always Show Author is turned on), but I'd like to just not see anything from these accounts. Not a perfect solution, but could be helpful.
Edit: Looks like the bot people don't like this idea since it's already being downvoted by accounts that no longer exist.

Edit 2: Just watching them come in. Up to 8 now and not one of these accounts exist any longer. Just proving my point that they really don't want to be filtered out.

This will just kick it a bit down the field, IMHO.
You mean the bots have to pre-game their shite-conveyor by making accounts a little earlier? If it's 2 weeks, then they have a delay as today's day of account building merely becomes the accounts they pump-and-dump in 2 weeks. And then it's regular capacity planning rules.
Some kind of graduated setup needs comment karma, though, so I have no easy fix.
Adding friction isn't a bad idea though.
Edit: s/fiction/friction
True, but it is something that could be implemented from a client side.
