I wasn’t referring to you, or Anne, or any of the volunteers when I said “site administrator”; I meant the people who actually get paid to maintain this site. This spam has been an ongoing problem for a long time and I haven’t seen any efforts to prevent it from happening. As I recall, the registration procedure uses a CAPTCHA method to verify real users, but it’s well known this is pretty easily defeated. There are a variety of other techniques to detect the spammers and any professional site administrator should be familiar with them. There are often modules that can be downloaded and installed in popular forum software that will do the job.
Ideally, a site administrator is a programmer and can write custom solutions to problems. For instance, I could stop these spammers by identifying posts with multiple links and disabling the accounts if they hadn’t been around for a while.
Please note I am not volunteering. This site is written in PHP and that isn’t my area of expertise. I could get it done, but it would be painful. A PHP programmer would find that easy to do. I could probably come up with dozens of ideas, but I really think the site admins already have a lot of tools they could implement. Unless they’re site designers, and not administrators by trade.
