Twitter is currently in the process of transitioning its profile pictures from one server to another, and apparently has made a change that is causing data woes for some Windows Phone users. Microsoft has confirmed that the built-in Twitter feature (within the People hub) is to blame for excessive data use reported by users.
In an attempt to provide a temporary solution for the problem, Microsoft has made changes to only sync Twitter accounts once per day, but has admitted its options are limited until Twitter resolves the back-end problem itself.
Removing a Twitter account from a Windows Phone device will stop the drain completely if you are concerned about data usage, until Twitter implements a permanent fix for the issue.
