Its not vote manipulation as such here. Its much simpler than that. Lemmy has a spam problem. People coming in to just make shill communities selling a service or product or spamming advert posts across communities.

They usually get downvoted, but I can use Piefeds admin tools to filter for downvoted posts by new accounts. This usually catches most spammers like that. I can then ban them from piefed.social and pass that on to Lemmy admins.

A lot of Day 1 trolls are caught like this too.

Sounds like a flood control for community creation would be appropriate.

It used to be in the early days instances would vet users at signup. Is there no mechanism for an instance admin to do the same for the creation of a community? They just can't be vetted before creation?

Piefed already disables community creation for out of the box accounts for a few days at least. Lemmy doesn't. That's the problem.

Also many of these spammers just spam on other communities rather than doing it on their own.
