How to detect spammers
When their is a language, there is a higher chance of being legit
List of users which have only N characters in the About Me (N=2, or other customizable numer). And delete the users, including their tracker info, and ban their IP (all of them possible in one single process).
It would be nice to have IP address of registrant in the confirmation email
It would be nice to just be able to reply the registration request to email the person and ask for more info
We should use a service like stopforumspam.com to provide an estimate of 0 to 10 of the likelihood this is a spammer and just ask more & more questions
When you delete a spammer, it should also offer to delete the user contributions (spam): comments to tiki objects and forum posts, like what is currently implemented for tracker items.
It would be nice to be able to make a list of all items in a tracker that are not associated to a user (perhaps leftover info from a deleted user...)
Should be possible to ban an e-mail from tiki-admin_banning.php
Would be nice in the validation email, to have the IP
Would be nice in the validation email, to have a link to directly delete the user account
