>>67861028I'd have agreed with you in 2009. But not any more.
/jp/ has become the true shithole. Most of its users can't even agree on what is on-topic and what isn't. The flood of retards has driven out almost all of the "old" /jp/ userbase and the shitposting levels are off the charts. Nobody knows how much of that is ironic shitposting, but ironic shitposting is still shitposting and doesn't help the board at all.
Also you're comparing an anime board with a NEET board, that's apples and oranges, obviously /jp/ is better if you want to tell people about your life and /a/ is better if you want anime discussion.
