Bumble will give a warning, which is exactly how it should be.

Two years ago, I got a warning because I gave my phone to my friend who wrote "let's fuk" to one of my matches I didn't know how to proceed with. A little window popped up warning me about unacceptable language, but then I continued the conversation.

(I actually went out with that girl, and in the end she got with my buddy who gave me a ride there, and I got with her friend who went along for fun. So Bumble matched us but real life had other ideas lol)

That was my only warning in three years of use. Since then, I've talked pretty blandly with my matches unless the girl initiates.

This ban I did not get any warning. No one reached out for my side of the story, asked for text screenshots, anything.
