question about twitter?

[Peter]

You got scammed. By logging in, you gave them your credentials and permission to post messages to twitter on your behalf. They're now using that to try to scam your friends as well. It's a pretty scummy thing to do. :-(

There's a couple of things you can do to fix it. Just changing your password might work. But to be sure, you want to log in to twitter and look at the list of applications that have permission to access your account. Hit the Settings link, then go to the "Connections" section. You'll get to a page that says "You've allowed the following applications to access your account", with a list of all the applications that are allowed to log in as you.

Hopefully the "get more fans" site will be listed with an obvious name. If you can find it, just click the "revoke access" link next to it and it'll be gone. If not, it might be best to just revoke access for everything you don't recognise.
