my weekly searchenginesercrets revealed v.4
 

... ok, as many of you may know from now on expired domains will lose their old pagerank when they get re-registered ... but guess what??

... try to find out the former whois info, and use it ... google will check the whois data, if it´s the same ... you won´t lose the old pagerank ... google does not care about the domains´s IP or nameservers ... have fun !!

Sneeky, I like it.

Is that legal?

That's pretty much illegal
if the former owner want his old domain back he'll get it soooooo easily

... I don´t think it´s legal, and of course I would never do that myself.

Thats assuming that Google relies solely on Whois Info, which is completely incorrect. Where do you get all this disinformation ?
