So - spam. It is very much out of control.
Here's why:
These aren't just bored individuals spamming the forum, they're highly organized companies.
Each time they come to the site, they change their IP address, and PURCHASE a new domain for their e-mail address. Every spammer has a perfectly accessible, valid e-mail address that they are able to validate and then post from. It's not an automated process, it's an actual person being paid pennies in a sweat-shop somewhere.
We're not the only site they're spamming, they've developed systems to work around every traditional measure that can currently be taken by any major forum software.
There are many, many other sites in the same predicament we are right now. We're currently in touch with a group of developers working on a mod for the board that may help dramatically - and we'll implement it as soon as we get our hands on it. We hope to have something in the next few days.
We want to avoid putting e-mail validation back in place. We received a lot of criticism when we did it the first time, and we've established that it will not help us in this particular situation.
Thank you all for your patience.
