I know there are spam checks on new user registrations, but is there really stuff in the forum code for more general spam checks ?
As I recall, before I changed my routing for the BBS, it would allow me to browse without logging in, but would not permit login over the VPN. I thought that, sure, maybe block new user registrations, but blocking an existing user from logging in? Peculiar.
Yep, it's the spam system then, it checks all logins as well as new user registrations. If it was the non spam IP blocking the forms have, anonymous browsing would have also been blocked.
The reasoning for the login checks is that a number of spammers were mass signing up for accounts on various boards while laying low. Weeks or months later, the spam posts would begin. Spam checking solutions bound only to new user registration were rendered ineffective and the software was upgraded to do checks at every login.
