My first account on the fediverse was on Beehaw and I was happy with it, but defederating from two of the largest instances gave me a reason to find a new instance. Personally I understand and respect the decision -that is the point of the fediverse afterall.
They had a lot of good communities that will not be cut off from the fastest growing instances which will make things tough to rebuild I think.
That response to your comment is good news. Ultimately, it sounds like Beehaw is open to refederating if they get access to better mod tools and/or those other instances institute similar measures to lemm.ee.
