Whos fault it is matters because that determines who is going to fix it.
If the wrong party attempts to fix it you wind up with a hacked solution that isnt going to be useful across platforms.
The simple solution to this from fedisearch side, and what I'd personally recommend, would be to check each profile of a reply and see if it has a no-index metatag. If it does then dont index the reply.
This would be an easy solution, standards compliant, and would address your concerns in as reasonable a way as is possible.
