Where is everybody getting these links from?!

Guys, I'm curious like what link building service this would be like it's all these blogs writtin on the sub domain.

When I buy links are all from like foreign places and like these are actually not super bad how would I get a hold of these

Most of those domains in the screenshot come from Money Robot. They are set up to look like real web2.0/free blog sites but if you submit content through a browser rather than through the Money Robot interface your content will be deleted with a day or so.
