I host my blog on a hosted VM - I am in control of the server. Right now, my blog is getting massive amounts of spam from Ubiquity Server Solutions (aka Nobis Technology Group). I've identified this provider via Google Analytics.
Apparently I'm not the only one this is happening to:

I'm a total newbie when it comes to admin - can anyone give me some simple steps to mitigate against this flood of spam I'm getting (500/600 some days)? And could this affect my SEO?
