if it's advertised over blf, has blf players, and has a whitelist, it could be good
bad news for you
BLF-only servers often are clown fiestas because forumers tend to be A.) younger and more apt to making bad decisions, B.) try to forget stuff up 24/7, and C.) one day magically stop coming on the server.
I've tried hosting three separate times. None lasted longer than a couple weeks. I just host my own public server now because BLF only ones are bad in every conceivable way.
