Don't increase post count in forum, but KEEP current posts

[Lpspider]

I want to make it so post count doesn't increase for a certain forum - however, I don't want to remove a users current posts.

Any hack like this out? I couldn't find it. Anyone want to develope it?

Go to the ACP Forum Manager -> Edit Forum and set 'Count Posts Made in this Forum Towards User Post Counts' to no.

But that will make all posts in that forum previously to not count, decreasing their post count - will it not?

I want them to KEEP all current posts as post count, but future ones to not count.

If someone could at least confirm the above that'd be great.
