I don't quite get how migrations work. They seem to reset the score but..also not always? I've definitely been able to vote on a question before and after a migration. I think it was upvotes, though. Maybe it wipes downvotes? It might also similarly wipe flags.
I mean, realistically, it's not "wiping" them. It's creating a new post and locking/removing the old one. So anything related to the old post doesn't transfer. But I have seen the votes transfer.
do we ever preemptively watch numbers? This is somewhere on the spectrum from dumb question to spam attempt, and it includes the number which would be spammed if it turns out to be part of a campaign
