First of all, It's annoying to read that people take an disparaging tone towards someone who only tries to make the life better for both forum owner and visitors alike.
I don't like being dependent on Captcha's that involve advanced graphology classes or hinder people with visual disabilities such as colour blindness.
One of the biggest upside of this methodology for me his solution runs completely server side so no funky minimal browser specifications one needs to meet. Not many anti-spam solutions can say that can they?
Anyway, Martin makes a very valid point. People being kept out (for whatever VALID reasons) by a Captcha is just as much a false positive and equally "bad" to a false positive on a IPRBL or the likes, but I don't see anybody bother quantifying those stats... I guess those users don't exists
The whole "You need to configure it, so it's bad!" is just another fallacy in my book. Life isn't that black and white and so isn't tackling spam.
Like any other anti-spam solution there is an option to disable it.
If you don't like it don't use it. My experiences with this mod have been quite good and yes it takes some time to weight (some may want to rethink why this is actually required) the various block lists but once you have done that it is second to no other spam solution developed for Olympus.
Especially for some of you who should know better, SPAM these days is an organic beast that needs an organic approach and tooling to battle.
Bottom line is that there are already plenty of Captcha "solutions" already, time for adding more tools with different approaches to the arsenal. Just because people don't like or didn't bother to configure it to a state it is acceptable to them shouldn't be a reason to dismiss it.
In closing it would be a good moment for some people to read THIS
Ps. It's kind of ironic that people are queuing up to have just the Akismet blocking incorporated while it is part of this module.
