XF 1.5 Find all posts in a forum by anyone not in usergroup X?

[Ludachris]

We have paid advertiser usergroup that is granted access to a special forum where they can promote themselves. The problem is, we have quite a few threads in that forum now that are still publicly visible even though the member who posted is no longer an advertiser. I'm looking for a way to identify all posts in that forum where the thread starter isn't part of a specific usergroup so that the threads can be soft deleted. My first thought was to use the Batch Update process, but I saw from another thread that this wouldn't be advised, and I don't even think it's possible anyway. What other options do I have to achieve this?

Thanks in advance.

There isn't a way to do that short of doing it manually.
