Thanks for this thread!
As far as I know, Groundspeak is taking some measures against the release of mystery / multi / letterbox solutions.
Log entries that spoiler solutions may be deleted by the owner, the same applies to pictures:
Statement of the german reviewers - cachers could be banned:
In my view, there is a lack of respect for mystery owners & creators when solutions are spoiled and shared.
It is also a sign of weakness and nonsense for me if someone logged hundreds or thousands of such mystery caches, just for the sake of statistics only to have the corresponding number of mystery finds.
TravelBugs with published tracking codes can be locked by Groundspeak. Especially with expensive geocoins, such cachers harm the owners - even financially, because these coins are no longer worth anything, e.g. in exchange transactions.
It is an absolute insolence to write, someone can lock the own TB / Geocoin to prevent logs!
I bought my Geocoins to let them be discovered by friends - not by asholes like those facebook group members. Therfore I will delete such unwanted logs!
These are all reasons why I hate such manipulating statistics cachers and why I describe myself als pleasure-cacher. I am very happy that I have already found many true cacher friends with the same conviction.
I have some geocoins that I haven't activated yet. My friends admire this without being able to discover them. Simply out of respect for the collection itself.
Project-GC could blacklist the tracking codes from the spoiler pages / facebook groups:
Then if e.g. some codes abcd001, abcd002, abcd003, ... occur at the same time in one discover job, this could simply be canceled with an indication of "There is suspicion of fraud, your account ID has been registerd, in the case of repetitions you will be excluded from PGC an be reported to Groundspeak".
It could also be dangerous for PGC if those fraud published tracking codes are supported in future by the TB discover tool. Groundspeak could deprive PGC of using the API, because it is supporting such a scam.
