Your sock-puppets have been disabled. The other new accounts have all been successful (10 in the last 24 hours). So we are hardly banning "them all, as you have been doing."
Only noticed, oh, four? new users posting. UIDs over 25,000?
Taking into consideration that there is a bot creating around 100 fake accounts a day I am entirely happy with the count of new users - which you seem to have under-calculated. Perhaps you are not including those who moderate or make submissions, or who have accounts but chose to post as AC on the front pages anyway. Of course, that wouldn't support your claims quite so well, would it?
