Remember that it's a game and different people play differently. Since there is no prize at the end (other than one's own feeling of accomplishment) who cares if people armchair your caches? The armchair cacher's are only displaying that they don't play the game the way that I do. Perhaps they are of limited mobility, are virtual caching, and something about the title of the cache intrigued them.
However, I don't think that is any excuse for multiple logs.
Wait. Maybe they liked the cache a lot so the went and virtually found it a few times. Maybe they like their find count going up with multiple finds. If we all play differently.....
We DO all play by different rules. So you can't like armchair caching and not like multiple logs.
But I see a distinction with a CO deleting logs. The CO can delete any logs that don't have signatures on the cache log. That is based on a RULE.
Armchair caching / seeing but not signing -- that's a playing style/choice. And, at least theoretically, you risk your smileys if you have not signed the log. A CO choosing to delete a log -- that's enforcing an actual rule. The playing style for the CO is whether the CO chooses to do that or not. But deleting is based on a rule, not just a random playing style.
