I noticed on one of my other sites that there has been a lot of spam registration going on!
Most of the time, the spamming ends with the registration, but sometimes, they end up posting crap.
I upgraded to the latest forum software version and also implemented an anti-spam bot measure that stops the automatic registration from the spammers.
I will be doing the same thing here on this site within the next day or so.
In the meantime, I have already deleted a bunch of bogus accounts here on V8Roadsters.com
Sorry if there has been any inconvenience.
