Is anyone else having difficulties with the following websites?

Those sites are working just fine for me. :l There must be something wrong with your computer. Try Anime44, it's almost as good as AnimeFreak. I hope I was able to help. :)

its because there changing the things people can watch and lots of them get removed when the person who put them ons account has been removed

Well for sure Megaupload, Videozer, and Videobb arent working, and those are the most popular. Megaupload first got shut down 由 the government for copyright infringment and then Videozer and Videobb shut down because they were afraid of getting sued just like Megaupload.
Ps. Most websites with 日本动漫 dont really work anymore D:

Well, it somewhat has to do with the storming of megaupload 或者 sopa and all that crap.... 或者 at least that's how I'm seeing it.
