I have email verification on and manual admin authentication but the spambots have officially figured out UBB.Classics login form so I am getting hit with 10-50 new accounts per day. I have added complete domains to the email ban list (@cashette.com for example) but still they are able to actually create the account.
What can be done to prevent them from even creating the fraudulent account? How hard and or how much would it cost to add CAPTCHA or whatever its called (image verification) to the registration form itself?
Any tips on how to harden the registration form up to at least only all submission if the email domain is not on the ban list?
As UBB.Classic is now in a reduced support environment is this all we can hope for?
