if you have previously used the Ui method ( search the forum if you do not know what this is )
you will have noticed ( and maybe think it is detected )
it is and it is not,
the reason you get a kick on certain servers is the admins stupidity
http://forums.bistudio.com/showthread.php?t=129168certain servers have not installed the hotfix , which meens they cannot run bi sign checking due to mismatched sign files of languagecore
you will be able to join those specific servers until they update to the hotfix with any pbo not just ui.
note: ui is full detected on servers with the hotfix and bisign 2 check , sign 1 is deprected now.
have fun and happy mod-apping
