Twitter just blocked UberMedia’s Twitter client, UberTwitter.

In the process it knocked a whole bunch of its most popular celebrities off Twitter (for the moment).

The brain droppings of these celebs are a huge reason lots of consumers use Twitter, so we bet Twitter the company is doing its best to reach out and convert them to new apps.

Five of them are:

• TV actor Donnie Wahlberg, with 163,632 followers.
• Questo of The Roots, with 1,478,297 followers
• Producer Russell Simmons, with 642,382 followers.
• Lance Armstrong, with 2,743,762 followers.
• Pop starlet Rihanna, with 3,399,061 followers

Twitter knocked out UberMedia mostly because it’s afraid of one entreprenuer named Bill Gross. Click here to find out why.

In the meantime, here’s UberMedia’s statement:

PASADENA, CA – February 18, 2011 – Early Friday morning, Twitter shut off access to its service by several of our Twitter client applications:  UberTwitter, Twidroyd, and UberCurrent.  Twitter then notified us that they believed we were in violation of several provisions of their terms of service.

We were immediately in touch with Twitter, and the changes they asked us to make were very small.  As a result, we have completed the changes, and new apps are currently being posted to their respective stores.  Twitter has assured us that as soon as those changes were complete, they would reactivate our applications.

Twitter also asked us to modify the name of UberTwitter.  We began a process of changing the name three weeks ago by polling our users, and we’ve decided based on their input to change the product name to UberSocial, which we completed today.

To our millions of loyal users, we appreciate your patience during this temporary period.  We look forward to continuing our innovations on the Twitter platform.
