No, everything about his little handiwork was bad, but there are law’s against nazi symbolism in Germany. The guy chose to use the short word “Scheiss” for “shitty” and specifically wrote it with the replacement double S instead of the normal ß at the end, just so he could cram in a nazi symbol. So yeah, he went above and beyond to get in trouble.

The other stuff is bad as well, but he could maybe argue his way out of it as laws about it are kinda vague.
