Most of their domains are rated as "spam" from Joe Wein's lists, but they're much worse than that.
mightysuch.com
isn't spammed. They hacked a legitimate website and inserted a file redirecting to mightysuch.com, then spammed that URL. The particular link I got was to a site whose registration information say the domain is available, so I guess I was seeing a cached copy and the domain owner has already lost his website.
The Canadian Pharmacy spammers do a lot of hacking websites to insert pages with redirections to their sites. They often insert copies of malware on the same sites and use phishing to try to get people to download them. They were heavily into Storm Worm when that was popular.
Here's some more that use the same nameservers:
devoutpaint.com
shorttangy.com
ownequate.com
hugeduring.com
finestslip.com
scoreput.com
And some a little older
