here I don't see problems, with the patch now the server is immune versus the attack "swbfp -v 61 -g SERVER".
if you refer to the fake players in the sense of stopping the ability of one IP address to fill more slots, that one is not the purpose of the patch which has been created for fixing the 7guests specific bug.
for the fake players limitation take a look to its project:
