Restoring accidentally suspended accounts 4 days ago

Earlier today, we accidentally suspended a number of accounts.

We regret the human error that led to these mistaken suspensions and we are working to restore the affected accounts—we expect this to be completed in the next several hours.

One additional note: some the accounts suspended were using the third-party site Tweetlater. However, Tweetlater is not to blame for these suspensions nor is it in violation of our Terms.
