pruning members

[jakaroo]

I am running 2 forums and they both have so many spammers signing up each day it became a pain. I did put in a extra question in the registration process which drastically helps me decide who is there to join in and who is there to spam....but...now all my registrations have to be activated by me before anyone can post that is legit.

my question is... is there anyways that I can automatically sort all my registrations by the question that i asked... where it will show up like the join date and email on the prune user page? then I can quickly select the ones that do not answer my question and delete them all at once instead of having to go to each and every user and see if they answered the question properly..... it takes forever to sort through each one.

thanks for any and all help on how I can sort through these users. if I can go in and automatically delete the ones that don't answer the question or answer it wrong at a quick glance, it would save hours a day!
