On my site it says I have 440 members, I had 4,500 last week.
I think I stuffed up with prunning.
All the 4,500 members are still in the database.
Question is: how do I "reactive" those that don't appear on the site membership, so that they are still linked to their previous posts?

So you're saying they're in the database but aren't on the memberlist?? Because the memberlist pulls directly from the database so that doesn't make much sense...
