Can someone help me fix a stupid Twitter "mistake"?

[CompententlyCatastrophic]

I visited the site that says "Get more Twitter Followers" cause I heard a lot about it and I wanted to see who would do it, and what it did. NOW, they're sending generic tweets to all of my friends saying "I visited this page...blah, blah, blah". Is there any way to stop them from doing that???? I didn't want the followers- I deleted the ones they automatically gave me and now my friends are getting irritated. Help!?

PS- Yes, I know I shouldn't have visited the site if I didn't want something like that to happen, but I didn't know. And NO- I'm not saving face- I really was just curious. Please, no rude comments- just answer if you know something that could help.
