Spam has been impossibly bad for over a month now. I finally, and reluctantly had to filter users less than two days old. I hated doing it because the new user garden needs love if it's going to grow but it's it's such a worthless shit fest on global nowadays that there was no other legitimate option.
I've mentioned that it's a problem that needs attention many times but the only result has been late and insufficient culling of spam posts. It's a bad sign for Hubski when you can't see the trees for all the weeds.
