Recently I noticed a growing number of NA postings by GC "members" who - according to their profiles - don't have any finds.
From my personal point of view, there are several things to be said about this phenomenon:
1. If they are really totally unexperienced members, how were they able to gain the experience to decide whether to post a NA or not?
2. If they are not unexperienced users, already found a lot of caches and - as a result - are able to decide this, why don't they log their finds in order to prove that they don't run fake accounts?
3. If a fake account or an unexperienced user posts a NA, why should GS or any reviewer react to this posting? If a cache really violates the GS guidelines, there will surely be enough experienced members who post a NA themselves. But it is most likely that NA postings by unexperienced or fake users result from other reasons than any violation to GS guidelines - and therefore are in fact themselves a violation against the GS guidelines as far as I do understand them.
From my point of view, such postings are not much more than spam and should at least be ignored.
And from my point of view it would be an improvement to relieve the reviewers - along with the whole community - from such spam postings.
Probably the easiest way to achieve this, is to restrict the ability to post a NA to members with a specified minimum of finds - e.g. 50.
Additionally I would suggest to ban member accounts without any finds, but a couple of NA postings instead, since they are most likely fake accounts, created only to attack some cache owners or the geocaching community as a whole.
