I had a similar thought; rebrand. If past allegations are a perpetual anchor around our neck, then change the name. Big companies do this all the time after a scandal.
I also think that being anon allows people to imagine us all as monsters so it might be useful to have a thread containing a letter written by Null with us all as signatories. Obviously, no one would put their name, but maybe more general information that would give us a little more legitimacy. 'PitcherInTheWheat- small business owner, member 3 years'
'whateverthefuck- teacher, member 5 years'
'somebodyelse- cancer researcher, member 7 years'
