The report is in German, but here’s a rough (very rough) Google translation:
The Vatican wanted the papal Twitter account @Pontifex closed because of the barrage of insults at times.“We did not think that some reactions would be so rough,” the president of the Pontifical Media Council, Archbishop Claudio Maria Celli said at a conference in Rome, according to Italian media. Some negative comments were expected, but what had made him suffer, was “the vulgarity, rudeness,” said Celli.
He said that after careful consideration, the Vatican decided to keep the channel open.
“Providence has helped us,” Celli said, referring to the now 11.5 million followers of the Pope.
