First this thread ( http://forums.digitalpoint.com/showthread.php?p=7676133 ) brought my notice a new black hat technique, piggybagging trusted domain to rank for highly competitive words.. where posts a comment on a blogger blogs, and then provide back links to that comment page so that the comment itself ranks high... Today I saw that the profile page of a (non)member of propeller ranks for a very competitive keyword word like "buy viagra" propeller.com/member/peterviagram This member profile ranks 4th on the G-SERP for the keywords "Buy Viagra" See the wise use of the word viagra in the url string... It is become something like the fight between Anti Virus/Network security Companies Vs Virus coder/Hackers You get better everyday, and the hackers get even better!! Oh! the 6th rank is also a BEBO profile.. ( bebo.com/RuthM370 )I won't be surprised if the two are the same person... Or are they competitors? We are missing a Digg profile/linkedin profile here.... The whole member sites are open for ranking by these geniuses..
