OK, I've been away a while, but this stuff makes it totally unworthwhile even having this place bookmarked on the "show 10 most recent posts" page...
It is trivial to prevent, all new users require admin authorisation and authentication e-mail.
No email authenticated and admin authorised membership, no posting priviledges.
Perhaps you don't realise how much these spam scripts contribute to hogging the server and slowing it down for everyone else....
Also worth pointing out that this board is running version 1.05, while the latest release version is 1.1.3, this also attracts malicious activity....
Make no mistake, this issue takes literally a few minutes and a few mouseclicks to check radio boxes in the admin area to fix.
If it isn't fixed pronto the problems will get worse, and I'm sure I won't be alone is just walking away from it.
cheers
