I've seen a bunch of different things. I was at one event where I got introduced to someone who had tens of thousands of cache finds. Then I watched as the person sat in their car the entire day driving people to and from caches. People would call when they finished a chunk of caches, he'd pick them up, drop them off somewhere else, then go get another group. I cached with a group for a bit, and they told me all the caches I could log and what team to say I was part of. I just said thanks, and only logged the caches I physically found. So I know people are doing what the original poster is mentioning.
On the other hand, though, as far as does it bother me? No, I don't really care how other people play the game. I play to have fun, not to look at other people's stats, or worry about how other people are playing. Other people play differently, and that's fine, provided they don't bother me about how I'm playing. And while I understand that some people will start removing their caches if they suspect people are finding them like this, other people will likely place new ones.
