I'm under a 302 redirection hijacking, my website was replaced in serp by a competitor !

hi, since some days someone is using a 302 hijacking redirection on my website
more information about this attack here: http://www.loriswebs.com/hijacking_web_pages.html

so google gave him all my pagerank and authority, so my website were replaced in serp by hijacker's website !

note: he doesn't own my google webmaster
my hosting is secured like my registrar logins etc
he make this only with some very high pr domains which copy my content and description so Google think that its my new website..
Someone have an idea for block this attack ?

Why new thread, many people members already answered your question here http://www.blackhatworld.com/blackh...rp-my-website-old-domain-301-redirection.html

The thread you pointed us to does not provide an answer, and it's convoluted with diagnosis of a specific site. Having a consolidated thread is important (but only if it helps provide clarity to the primary issue). 302 redirects are not new. Just very short lived.
