Okay we all hate random spammers posting in your forums.
We hear people crying everyday.

I have looked at some of the plugins posted on vbulletin.org and they are quite neat plugins.
On my board I have a custom field for everyone to write something in the box, all these spammers have their name in this box so that I can identify these accounts pretty easy.
My request is that could someone build me a small plugin so that people cannot sign up on my board when their nickname(alias) is the same as what they have in the custom field?
