I don't deal with proxies, instead I assemble all the content, highlight where to interlink it, show where to link to my site(s) and other authority sites, gather pictures, video links, make logos, and all the other fun stuff; then I hire someone off seoclerks for between $2-3 per web2 and have them register it, verify it and then upload the content.
When they do a good job, I hire them for other tasks as needed. So they are motivated to do a good job.
It costs me just a couple bucks and I end up with a web2 that is interlinked, with a link to my site, with content scheduled out for months.
Just easier for me.
