Like rinkan mentioned, the admins have been pretty outspoken about how being free speech oriented is not the same as being a bunch of assholes. For example, from this featured post:
What Burggit is not
We are not another Kiwifarms, Gab or Voat!
While we’re fine with people posting offensive speech and imagery, we won’t allow them to use their right to “Free Speech” as a weapon against the overall health of the platform. Threatening, Berating, Dogpiling, Doxxing and otherwise being complete and total assholes to other users will not be tolerated.
