Which CMS is this? interesting...
 

I want to know which CMS script use those sites.

videosxgratis.net

xxxbitch.net

bitchgirl.net

verybitch.com

I think this is not a custom made

thank you

do you know guys? I think it's a public cms

I'm not sure what CMS is being used by each site, it just looks like the same layout or design is being used. I don't think it has anything to do with the CMS. I'm sure you can tweek most content management systems to run with such a layout.
