May I say that whatever you decide to do, you've already "won" this? First, giving a shit about people, and second, spending time grappling with those truthfully complex issues has enriched you, and all of us.
One suggestion is to edit them with wording like fuck spez, so that if he deletes your content it won't be you that yanked it away from people.
But they could just revert that easily enough, rather than delete outright (although are they smart enough to do that...?). Another could be to insert an explanation at the top or bottom of all your (best/all) stuff that you do not condone Reddit's actions but decided not to punish end-users for the actions of that powermod abuser.
And eventually you could migrate it elsewhere but yeah, that's a bit hard to do atm when users would have trouble finding it. OR, you could combine these approaches: for each answer, make a post to kbin/lemmy about the issue, then edit the original to include solely a link to that new location. That would kill 2 birds with 1 stone by helping people realize where to go for high-quality content, while providing the direct answer (there's no need to create an account or deal with fediverse issues, anyone at all can just read it). (The down-side is that spez could easily revert that back too, but if so then you could keep trying, like spell out the link to futz with its automated detection.)
But whatever you end up doing, I see that you are doing it because you care, and that's already a win in my book. :-)
