No matter what I do on the back end - the spamming doesn't stop. The spam-bots have figured out how to register, and are posting like crazy.
Therefore, I'm going to require all comments - even from registered users, to be approved until I can fix the problem.
This blog will be dumping Drupal CMS soon, and the problems should end.
Sorry for the inconvience.
As a programmer I would suggest the problem is the "Math Question" field is far too easy to defeat as a tool for separating humans from spambots.
As a professional programmer, I can write a simple Visual Basic Program that can read the raw HTML text from your website, parse out the question, and formulate an automated reply to defeat your human tester.
I suspect this is exactly how you are being overwhelmed by apparently "gay" and supremely irritating spambots - although not by me.
A far stronger technique would be the "distorted bitmap" text that OCR based software cannot effectively read but humans can. Many websites use this technique these days (such as the Orlando Sentinel) to separate the beings from the bots.
I would believe that such modules are available both for Drupal and Joomla.
I am working on setting up a Joomla based site myself and find it a lot easier to understand than the Drupal CMS.
I hope things start improving soon and I sent you a piece this morning (although it is likely too long) that I hope you can use in some fashion.
Instead of a simple math question, turn it into a round of Jeopardy and require the spambot to know answers to inane trivia like:
Who won the 1969 World Series?
Who was the 15th President of the United States?
What element has an atomic weight of 235 and atomic number of 92?
What is the distance from the earth to the sun?
What is the capitol of New Hampshire?
Who signed the Declaration of Independence for the State of Georgia?
What year did the Corvette first appear?
What year did the U.S. Air Force become a separate military service?
What date did Richard Nixon resign on?
What day was the Presidential general election in 2004?
Who was Gerald Ford's Vice President?
What branch of the military did Ted Williams serve in?
What branch of the military did Jimmy Stuart serve in?
What was Woodrow Wilson's wife's maiden name?
etc..etc..
I think this sort of question would be much harder for the spambot to know the answer... Spambots are pretty dumb..they must be since they keep posting the same thing over and over - apparently they can do simple addition but I'd bet they'd probably lose on Jeopardy.
