The story runs as follow. Account was opened in Twitter under La Russa; it was a fake account. Some claimed that under threat of lawsuit, Twitter (the company) closed the account and donated money to charity. Twitter denied the story.
Two things spring to mind. Is the fake account doing any harm, for example by impersonating a real life person so well one could not easily guess what was true and false? if so, civil law at least applies and Twitter can delete the account. However, there should be court proceedings rather than threats and bullying.
