How many caches should a single person be allowed to own, is it 50 or 200 or 1779. I doubt if the reviewers or geocaching.com are that bothered, they are after all only interested in numbers.
Sorry, but that’s a bit of a silly arguement IMO – the only judgement is the ability to maintain them in a timely fashion. There’s no suggestion poshrule performs maint any less rigorously than any other CO despite having so many, and there are lots of cache owners whose caches are forcibly archived because they fail to do any maint even when they only have one or a few caches.
In my view, there should be fewer rules in geocaching, not more.
