we made our own system, because all the stuff out there now either requires you to install the cms software for each domain/website you want to do, those that are there for porn only focus on one aspect, (tube, basic management, etc).
the system we made can handle unlimited websites/domains, is custom tuned for anything we want it to do, and is completely secured from any of the websites it handles (unlike just about all the other cms's out there which put the admin in a /admin like folder, which any numbnutz can figure out how to crack in to). As well since we have a rather large set of servers, we built in server management software into the cms to monitor over and handle issues for all our servers which can grow/shrink as needed.
There's alot of really good cms's out there, but again depending on what you're looking to accomplish none of them handle it all at the same time, so we opted to make something that we'd never have to look for something else to do.
