I’m not sure how it would be done exactly but there needs to be a way to verify new users joining the forum. Maybe require a phone number and only allow a few accounts to use that number before it gets barred.
I’m seeing quite often the forum is getting spammed with Chinese forum posts advertising a site of some kind (im not 100% sure, I dont speak Chinese). It’s getting spammed by accounts that are brand new and I wouldn’t be surprised if new users avoided the forum because of this stuff.
edit. a quick google search shows this is definitely popular spam on other forums. Something needs to be done.
