A lot of people on the site like them. Just like news posts about Fun., FOB posts aren't going to disappear because some people are tired of reading about them (which you actually don't have to do, by the way).
I understand completely, P.S. I have blocked this band from my news feed NUMEROUS times, yet somehow it seeps through... also Fun. is an extremely talented band who (I feel) are 100% deserving of their success. Fall Out Boy seems like a band who saw the attention Blink-182 got by going on hiatus and followed in their footsteps almost as a marketing strategy. I'm 100% positive the "reunion" was planned from the start. Pete Wentz is a fucking tool, but I'm sure he's smart enough to know Ashley Simpsons albums sales won't pay his bills forever.
