I always found this Code-of-conduct stuff ridiculous. Can you just go to the organizers, finger-point at somebody else and yell "muh feelingz are hurt" and the accused person will be kicked out? Does it really work that way?

Germany has laws on harassment, and so does probably every other western country. If you've been harassed, it is your right to go to the police and press charges.

And ffs, don't do fingerpointing on Twitter. We don't live in the dark ages, we don't burn witches anymore.
