hi everyone . I bought cheap year host plan to one of my sites after I run out money due to issue with visa card on my country I check sites hosted with my site and found 90% are pure spam site like some adult affiliate LQ PBN sites . I know G not saying it directly but this high number of spammy sites on one server could alert red flag . on the other hand I moved my second site from shared host to VPS immediately visitors drooped from 480/day to 100 and I lost all my ranking on G . I used the VPS to host my other sites on single IP currently I have two sites on it the other on I bought it from Godaddy auction have PR2 and no spammy links . All I notice that G do weird thing to penalties site according to their IP likes they have their Black list .
