The latest site from MG Dot Advertising: negativeseoss.com — currently hosted at 104.27.136.15 by Cloudfare.com, a company that seems to specialize in hosting sites for spammers selling counterfeit goods and other dubious fare. They seem to be catching on to the fact that the name "MG Dot Advertising" is becoming well known (and not in a good way) because they scrupulously hide it. It's not on the negativeseoss.com page itself but when you click on a "buy" button the page that opens is www1.mg-cart.net, which says "MGDot Advertising Agency 001 (516) 926-1772, 18 Richmond St, Albany, New York, USA". Yup. Same scumbags.

DomainTools says the registrar is Tucows (which has long had problems vetting its clients).
And the servers hosting the site are on Cloudflare.com, which also hosts that AWEFUL site 800notes.com

It's a shame 800notes is on a scummy host like Cloudfare.com. Then again, spammy providers like to host legit sites, too. Legit sites like 800notes serve as "human shields", so to speak, to convince people not to firewall/blacklist their network.

SSDD (Same Scammers, Different Domain). They've added mgdots.net now (104.27.156.248 — yes, it's Cloudfare.com). This site is just a clone of various other ones they've had and doesn't try to hide its ownership: "MGDot Advertising Agency 001 (516) 926-1772, 18 Richmond St, Albany, New York, USA".

The MG Dot Advertising scammers just added another web site — thewebsitetraffic.net — over the weekend. But kudos to Cloudflare.com for shutting it down within 24 hours. It'll probably turn up on a Chinese host within a few days...
