Almost all of the spam I have seen is coming from one company.
The admins just need to report them and they should be taken down.
Their registrar is register.com and I think their host is weebly.com.
This assumes that this isn't being done by a competitor of theirs to cause them flack.
direct-saleslimited.com
The IP of 199.34.228.100 goes to Weebly.com

I should add that they are known to spam from IP's
63.141.237.105 and
79.143.179.42.

If you search the company name you will see forum after forum spammed. Since I am not an admin on this site I can not verify the spam truly originates from them and not an evil competitor.
