The site operates on a decentralized model: when one domain is seized or banned by ISPs, the administrators quickly launch a new domain. This cat-and-mouse game with authorities explains the frequent need for "UPD" or "updated" links.

I’m not sure what you mean by “9x Movies. Nl UPD.” I’ll assume you want a short piece (summary/overview) about 9xMovies and a brief update (NL = Netherlands? or NL = new/latest?). I’ll pick a concise, informative overview plus a short update about legal/status issues. If you meant something else, tell me.
