On some forums when you sign up it has a human verification that is not capcha.

It asks "The name of this forum is dy_____ ______"

If in the perl script that the form connects to it has


If forumname != namic forums then
error.

and


If forumname = namic forums then send email

Would that stop bots the same way that capcha does?

It will help, but only if the CGI-Bin directory is inaccessible to all visitors. The good news is, on most reliable server hosts this is default.

Bots aren't really capable of guessing-- they're programmed. The reason that an image is used is because those images are very hard to program a bot to read. So, it is not hard at all to program a bot to enter that value. It must be a bit random and hard to guess, or at least not enough of a target that someone will reprogram a bot.
