Twitter suspends my account but gives no reason

I wanted to tweet something today morning and instead I am blogging about how I can't. Thats because Twitter has decided to suspend my account without giving any reason. Now a service provider has the right to withdraw the service at any given time but I think they owe an explanation at least to the user. But Twitter doesn't think so. The only message I got was a warning box on top of my page which informed me about the suspension.

To top it all, the email they sent me, after I sent an application for reinstating the account, asks me to explain if I knew why the account has been suspended!!. No, I did not do anything that violates the rules.

I know I am not the first one to get knocked out. Sometime back twitter accidently suspended a number of accounts due to human error. My grouse is with the secrecy around such an action. Talk about social network being "open".

So if you are trying to find me on Twitter and you can't, it's because Twitter has suspended my account. I am just hoping that its another human error or their computer automatically locked me out of my account. Twitter please give me back my account.

UPDATE:

Twitter has restored my account after two weeks and after I had made a new account. Got a mail from them saying that my account got suspended by mistake along with some spammers.
