Help!!! My Website Has Disappeared from All Search Engines!!!

Ok this happened a week ago... and actually I didnt pinpoint the problem till wednesday... and didnt find this forum till today

My website http://angelic-anime.tk or http://futurenet.ath.cs/sdomain (either or) used to be all over google and other search engines. I would get 1000+ hits a day As of a week ago, all but maybe 2 links "disappeared" from every search engine out there O_O My wallpapers, which used to provided me about 300 hits a day from google images, all links GONE!!! I am down to 50-150 a day Well, I know it says I have not many loyal visitors... lol, but well why is my website gone!?! I didnt chnage any Metas, or netin... and my host(my friend who runs a server), has no clue, seeing his site, futurenet.ath.cx or his dads(based on the same server) do appear.... just mine doesnt O_O" Even my other sites based from older hosts, disappeared as well. Can anyone help?

Did one of those domains redirect to the other, or was one a copy of the other site? If one was a copy then you probably got a duplicate content penalty. If it was a redirect, was it a 301 or 302? sometimes 302 can cause problems with search engines.

Erm, actually I only submitted teh 2nd one(futurenet.....) the .tk was one I was trying to get people to use, seeing well, its a cheap redirect domain so it wont show up as well neway :P Im not sure about the 301/302 thing.... but Ive had http://futurenet.ath.cs/sdomain as the link for 2 years(content, and what the site was about has changed though), and not until a week ago did this happen o.O.

Also actually 1 page is still in google o.O And it isnt even a highly important page :/

If you have renamed or moved the pages you visitors be getting 404 errors and your moved pages will not get many hits until they are reindexed.

This may seem a stupid thing to say, but consider hard. Has the HTTP server configuration been changed, the root or any directories renamed or moved? Script access changed, PHP, ASP files? A small change may result in the URLs in the search engine becomming invalid. This can include access rights on the file system or HTTP server.

if you have 2 domain's on different IP's with duplicate content you will lose a good deal of rank from almost every search engine spider (they hate copy and pasted content).

Also invalid or slow responding pages hurt your rank.

maybe someone has removed yur website from google, by filling the required details

Is it possible? How can we remove our site from google.
