Hi Niels,
Thanks for your reply, a summary of years of debates . I must said I don't have read accurately the full subject.
As a "noob" in geocaching but little skilled in computer applications management I believe this problem can be solved (or we can try to) involving people. The global Geocaching activities relying on people and ONLY people, giving their best for fun. Involving all geocachers in TB database purge sounds a good solution, regarding the technical means.
And we can easily said that it can't be worst than today situation to try something ...
Hope something will move on this subject.
Cheers,
Phil
PS: Funny to see you're from Almere, I went there for a "special" event in 1997, a nice place ( https://nl.wikipedia.org/wiki/Hacking_in_Progress ). Some wonderful souvenirs !
