Hello,
I have 60 caches, and since last week some people write logs 4 times and more often.
This is not normal, there are too many that can not be a coincidence.
Examples:
GC4AM5K - 09/08/13 from tombdig
GC4AM7Q - 10/08/13 from korvenei
GC4809F - 10/08/13 from lukas7-com
GC4AM5F - 10/08/13 from kommune 66
