There are 2 situations I have encountered when audit logs are useful…
1. If you set a high maintenance or complex cache (e.g. where stored equipment needs replenishing or stages need regular checking) it is useful to see when people are viewing your cache page, and how frequently they are doing so, as this can help give the cache setter an indication that someone is preparing to do the cache and they can make sure everything is in order. This situation is only likely to apply to a relatively small number of caches.
2. It can be interesting to the cache setter to see who is viewing their cache, especially when a new cache has been released, and particularly with puzzle/mystery caches. If you are part of a highly active local geocaching community it can be fun for the cache setter to be able to see who might be trying to solve their puzzle, and who is in the running for the first to find race. Remember that some geocachers get equal, or more, pleasure from producing well constructed caches and seeing them being solved as they do from the process of seeking caches. It’s a two-way sport involving setter & finder. In such circumstances if you wish to run an audit log you currently have to set the cache as a MOC thereby depriving non-members of the ability to do the cache. It is for this sort of situation I would like to be able to have an audit log but have the cache open to all.
In reply to some of the comments posted so far…
If a member only cache is ‘muggled’/goes missing, it’s going to be highly unlikely that a paid up member has done this, so looking at the audit log will not be of much value.
There may be ways of avoiding triggering an audit entry, but so what? If you wish to view caches in this manner to avoid ‘being seen’ that’s up to you.
I suspect it is very rare for people to email someone just because they have looked at their MOC and they live miles away. You were just unlucky.
