those gigs say such like that: post an article in 20 or more high pr web 2.0 sites and then build thousands of blog comments backlinks to these web 2.0 sites. how to do that? i ask here it is for making money. i see many gigs like this always have dozens of orders waiting to complete. i think that will make $3000-$10000 per month. and these gigs will complete within 24 hours. it seems that it is a easy making money method.
