having a real issue with a pest on my forums right now - he's using free email accounts to register and proxies to get round the banning he's had.
This has been going on for about 4 years now .. and he's determined to get on.
I've banned every IP, set admin activation - but because of the proxies and hotmail accounts he's using its difficult to identify real users.
What I wish to do is have the registraion form check the email domain and prevent registration from domains I specify, and to show an alert to advise this if they attempt to do so. I've checked on this site and cannot find something that won't ban the domains completely
I do not wish to ban the domains completely as I have a userbase of 6000+ existing users and it would be a mammoth task to prevent any existing users from being banned as a result of banning the domains.
If someone can help .. or direct me to an existing modification it would be much appreciated.
