No, it sounds like censorship. Apart from the fact that Gab is not a "Nazi server" just like your average Mastodon server is not a "Communist server" even though there may be some neo-Nazis on the former and are sure to be a number of communists on the latter it sounds like a petty action by the project maintainers if certain servers are blocked by default.

It sounds like a form of digital McCarthyism.

I'll have a look at the Pleroma source to see if they also engage in this type of ideological censorship. If not it sounds like Pleroma is the better alternative, being both lighter as well as (hopefully) free from censorship.

If it sounds petty, you should find the actual story. People generally don't take such extreme measures as banning an entire server from the network with no reason.

Having checked the Pleroma source [1] I can state that there are no default domain or user blocklists. It does support blocking on domain and user level but it is up to the administrator to provide blocklists.
