Nay.

Provided the moderators on sh.itjust.works feel capable of dealing with any outright hate speech or harassment from that community, I think most of us are big enough people we can deal with hearing differing view points. If someone has a big enough problem with a single user or community, there is always a user-side block as well. My only reservation would be if the degree of spam/harassment is over taxing our community moderators. I recall how many of us in sh.itjust.works were offended when Beehaw defederated us – for the same sort of reasons (too much spam, too much harassment, the wrong kind of people, etc etc etc).
