The ex-archbishop's @TutuLegacy account racked up hundreds of followers in its first hours of use. "Some have described Twitter as a blessing in the hands of retired members of the clergy.
There is no space to ramble," Tutu tweeted before his account was blocked. His foundation expressed dismay at the decision.
"Twitter has not explained how following 30 people could be construed as 'aggressive following'," it said in a statement. The foundation suggested "the number of people who followed @TutuLegacy in a short space of time," may have also been to blame.
"I hope the powers that be at Twitter find it in their hearts to fix the problem and let us communicate again," Tutu's daughter Mpho said. "We need to reassure all those people who started following us today that this is the real deal!"
