I was wondering, caus if it index it as 4 domains, couldn’t you just make, lets say 70000 subdomains and make them all link to your own homepage, and thereby get a high PR?
Look forward to some answers 
Do you really believe 70,000 subdomains linking to your own homepage will get your homepage a high PR?
It’s doesn’t matter how google treats subdomains nor how many subdomains will link to your homepage.. It’s more a question of how will the 70,000 sub domains will gain the PR to transfer to your hompage?
