What is so bad about the name Hilter?

Was banned on Twitch what should be bad at the name?

Hilter is a municipality in the south of the district of Osnabrück in Lower Saxony

Can you even think why that was banned there on Twitch.

It is a beautiful area, without a doubt. But it reads a bit like a native Austrian, who committed great crimes many years ago. I think you know who is meant
