Actually one of those domains I also tied into this thread

I'm wondering if it's the host themselves.. all those sites seem to be tied to powerpipe.com.
Back when I was starting out someone hooked me up with his "friend". It was some low cost hosting for a flat fee per month for galleries... It didn't take me long to discover that the hosting guy was redirecting my galleries.
