Please note that due to the high level of spammers using these free email domains that AMFone.net is not accepting new registrations for members using these email domains.
We receive sometimes 200+ spammer registration attempts and it's getting time consuming going through them trying to find the real members from the spammers.
You might be able to set up a "tag" filter, so that applicants have to put something like
"[subscription]" in their subject line. The vast majority of spammers use automated search engines to locate bulletin boards, and then they submit "vanilla" subscription requests for whatever type of BBS they find. A tag disrupts their process and buys you some breathing room, although you'll need to have lots of "readme" files to make sure everyone understands what's needed.
The key is to have some sort of CAPTCHA that will weed out the auto-subscribe robots.
HTH.
