About the “B.A.P” tag fucking up:
Don’t use the search bar. It gives you www.tumblr.com/search/b.a.p and yeah, that is a mess.
Instead switch /search/ for /tagged/, and you’ll get the properly tagged posts in chronological order with the most recent one on top.
This is the type of search I always use, tbh. That SEARCH shit is just for the most popular posts, and now they’ve gone and fucked that up.
