The "Nazi Bars"
For those who don't know, in "online jargon" when someone accuses a site or a platform of being a "Nazi Bar" that generally means that it tolerates nazis (however one defines/classifies these) and therefore signals to others that the "platform" (site/forum/social control media) isn't against their participation. Eventually, as non-nazis get disgusted and leave, the "platform" can become a Gab or a 4Chan.
"Nazi Bars" are not so uncommon, but most of these are unknown or invisible to most people. The "Linux world" had its own "Nazi (Mini)Bars" established in Twitter, now known as X and run by a man who does nazi salutes (MElon), even in public, allegedly craving attention.
We don't condone or condemn the label "Nazi Bar". It is actually useful in many contexts. █
