I think that's exactly the right thing to do here.

This particular mapper has replied to 2 of the 4 changeset discussion 
comments that people have left for them, so that might be an approach to 

With a DWG hat on I noticed edits my this mapper when looking at edits 
by another golf mapper ("TheMoneyTour") that were altogether wrong (that 
other mapper had changed main roads in the vicinity of courses to 
"cartpaths").  This mapper is still active, so if people see problematic 
golf edits like e.g. "resurrected" courses elsewhere, please email OSM's 
Data Working Group (via data at osmfoundation.org) about it.

What these mappers seem to be doing is adding golf-related features to 
OSM for use within golf simulators that use OSM for the base data.  
That's great where the features being added are accurate, but not so 
great when they're not.

Best Regards,

Andy (from the DWG)
