A few weeks ago you could find Gab (neo-nazi/white supremacist leaning instance) at the top of this list about most of the instances in the fediverse. Gab was a huge instance: ~1mln accounts, i.e. ~2x the number of accounts of Mastodon flagship instance. (numbers were inflated btw)
Why did Gab leave the fediverse? Because the rest of the fediverse campaigned to de-federate a neo-nazi/white supremacist instance. At the end of its story in the fediverse, Gab had an estimated insularity of 99.3% (source): that means 7 messages out of 1000 were directed outside that instance. The estimation is an upper limit, including outwards messages that actually cannot reach other instances (since these instances suspended Gab).
Now, according to the source above, Gab devs are discussing to drop the support for the fediverse. In the meantime, it is an insular instance.
