I see allot of clans who add passwords to their server... I'm not sure if it's possible but, creating some program that restricts players based on BL_ID would be cool.. So if someone joins w/ BL_ID '4000' and it wasn't on the whitelist they get kicked followed by, "Your not part of 'blank' clan"... I'm pretty sure it's creatable..
Reason instead of having a password is just because it would be less of a hassle.. You could have a clan application and just save every new BL_ID that's accepted..
Hmm.. Well just tell me if you like my idea.. and hopefully someone will create it ;)
