Whether she is a good or bad comedian is an opinion and she wasn't banned for changing her name. She was banned for impersonation. Last year more than 500k accounts were banned for that. It's not new.

"First, impersonation has always been banned on Twitter. Misleading profiles make Twitter worse for everyone. Last year, we banned more than half a million accounts for impersonating people and brands."
