This is a really good topic. There's one user in my area named JACOB. he owns 2407 caches all over!!!!! He can't and doesnt maintain them. It's insanely frustrating. He should NOT be allowed to own all those caches since it's pretty much impossible to maintain that many. I wish there was a way to red flag a user. Yes, he's clearly a dedicated cacher, but this just doesnt seem right.
Plus, it seems as if he rates them with ridiculous standards. For example, if you need to stand on a chair, he would will rate them as a terrain of 4 1/2 stars????
GC1CRKE is a cache I was recently after that is a good example of this. If you read the logs, you can see how rediculous the difficulty ratings are.
