Banned from twitter

Hi,
I've just been checking our twitter feed and was surprised to see Twitter had blocked our account due to spamming! It seems the twitter feed application within Sitefinity publishes content multiple times rather than just new items posted.

This has results in the past couple of days since we setup the broadcast, we have 6000 tweets!! Is there anyway of making sitefinity check whether it has tweeted a post with the same title in the past?
