if you mean Wayne I doubt he would do this.
We moved to new servers about a month ago. He does not have access to those. Plus his account here has been wiped of all but his posts.
We mods don't have server access nor access to a block list through vBulletin. Might be the same issue that was causing Franko password issues. I don't know. If some one did hack in. They don't like Franko, pretty short list on that. Also, a good reason to make sure that Apache, MySQL, PHP, and vBulletin are all up to date with current releases. At least no one has tried taking down the site. Assuming that it is a security hole issue. I just can't see any reason to block a whole ISP's address range.
