Why is kekw banned?

Excuse me, could you elaborate on the reason behind the ban of kekw? I'm quite intrigued to know the specifics behind this decision. Is it due to some kind of violation of terms of service, a security concern, or perhaps a matter of public decency? I would appreciate a clear and concise explanation as to why kekw has been banned, and what measures were taken to ensure that such bans are fair and just.
