Yep. You know, I have read more and more about DoS attacks lately. I've had websites since 1996 and I've never had an issue because of a denial of service attack. I suppose this is payback for when I used to be on the other end...
But anyway, I had to block a few IP addresses the other day from here, they were South America and China in origin. I wonder if they got pissed? I noticed it when I got on the forum and saw that we had 15 visitors and 2 members. It's common to have a few guests as some people are truely guests who don't want to log in, and that's ok. The other guests are usually bots from Google, Yahoo, and other search engine crawlers. That's ok too. But, the rest of the guests (like 7 of them) were all from nearly the same IP address, and they were registering for accounts and making errors happen. That's when I did something.
