Just from the thread title this sounds like a utterly crazy idea and something that goes against what imageboards are about but please keep reading. As most have noticed, majority of imageboards have either degenerated into constant flood of memes, shitposting, camwhoring and generally completely shitty content or then the boards are so small and post rate is so slow that viewing them isnt really worth the effort.

My idea to curb the general shitposting/spam/etc is to force people to make an account before they get to view the board. Go to url, get login page, maybe a register link or just text telling you to put /register after the url and make an account. After that you can view/post. No post would contain any nicknames or other name faggotry, it would be just a deterrent for people not to bother coming for cheap laughs and shitposting, bots and others. It would also allow moderators not only to ban but remove the account completely, forcing person to re-register if he wants to post again.

Besides of needing an account to view the content, the boards would function just like any other imageboard, have the same look and so on.

I dont know, this might be just a crazy idea not worth second thought but ive been thinking about this for some time now. I know, its rambling post and doesnt really make it clear how it would work but maybe somebody gets the general idea?
