Iv just notice that a russian website has Proxy Hijacked our website and got it indexed in G results.. We have noticed a steady decline in our SERP positions since end of Jan. I found the copy site by doing a "quote" search of the tittle in G.
Could someone give me some advice on how we can stop them doing this and would this be the reason for the drop in results.
p.s it looks like they have proxy hijack wikipedia as well 1000's of other well known sites.
Any help would be appreciated.
