Implementation of Registration Rules - Opinions needed

[闇の女王ヤミ]

... I am not an admin, so I dont have a possible flood of registrations to verify ^^ - That aside, I do have a feeling, that the current course with
a) no registration from proxies and
b) registration has to be admin-verified
is a well thought about and sensible plan to keep sniffer-bots and certain trolls out.
From my point of view it is perfectly OK, if you stick to that.
