Too many loving fort wars. They used to be cool until loving everyone started making them and now mine only gets 2-4 people in 3 hours. loving FNAF servers have been pretty ridiculous, I made a topic a couple weeks back. But one of the biggest things is that some of the older great server-makers have grown "too old" and "mature" for BL, plus there's the community that is rumored to be stuff (not my belief but I've heard it said a lot), and people also claim that Badspot won't update because he has lost interest. And on top of that, there are a lot of older users who are being imperialist to the new users simply because of a number, and that drives people away. People have just stopped playing in the past several months.
Bottom line, there's a reason for this decline in servers.
