I think voat was a, and this is cliche phrasing, boil the frog situation by Reddit.

Reddit kicked all of those worst people off and they migrated to voat before tightening again and pushing a lot of good faith users off. I remember being in a wave of people trying voat but when my wave arrived, the worst elements of Reddit had beaten us to it and had critical mass.

I think the fediverse situation is somewhat different since a large wave of good faith redditors have been pushed off in the last few weeks, and found Lemmy without it having a critical mass of awful people. At the end of the month, when 3PA shut down I’m sure there will be another wave of redditfugees and when they arrive, they’ll find this place as it is now so won’t be immediately repelled, unlike how I was repelled from voat.
