I am just wondering how these hackers find a Dolphin site to hake in all the billions of sites on the web.

I wonder if it is because some Unity members list there site url in there posts and/or in there membership info.

Hackers who are familiar with Dolphin and looking for sites to hack, are going to come to Unity and Expertzzz for a list of sites to try and hack. You do not have to even join these sites to get this information.

I am not saying that that you should not protect your site see more by make the necessary changes to the code and your server to protect your site, but for gods sake, stop making it easier for these hackers, by giving them the url to your site.
