Update the ingame rules.

And also, to answer your question: yes and no.

Yes, because staff is broken
No, because it's a goddamn emoji, and also, I never encountered any problems with Lenny while I was playing.

Also, just realised one thing: These characters are actually used as letters in languages, doesn't that mean those languages are also banned?

And yes I agree with that and if lennys are banned i guess they should be banned too.
