>the thread turns into thirst farming
That generally happens because they're looking for attention. Here are a couple of threads up right now in /j/:

>i have so much shows and anime to watch and so much manga to read...... i cant possible get it all in b4 summer ends.... its too much....

>Ozzy Osbourne is... is dead!

>I think boys should date other boys!

>My friend is in her tarot card phase and now she wont shut up about her predictions and tarot youtubers. I'm ok with tarot but I'm sick of hearing about it

>this site needs more yuri

Those are good threads that don't give away or rely on the gender of the user. All of which could appear on /b/ and no one would bat an eye


>i dont think dead threads matter all that much, if someone wants a fast paced site
Activity isn't the main issue. /jp/ is still conceptually justified despite not having many posts. Same goes with /lounge/, comparatively.
It's all about purpose. There 4 different porn boards that almost no one uses. Why?
