Should twitter based spammers be called spitters

Today I become fed up with someone I was following on twitter. I started following them and the tweets I got were great and full of nuggets every now and again. Then all of a sudden they started tweeting at an increasing amount. And they weren't the personal musings you'd expect but links to here, re-tweets to this... It was obviously no longer a single person. They became spam in my tweet stream, they filled up my tweets page, how annoying. So I no longer follow them... This did prompt the question in my mind, what is a twitter based spammer called? I figure it should be spitter!
