You can also use Google with the search terms "geocaching inurl:creepypasta" and "geocaching inurl:nosleep" to get results from offsite. A couple I found on Reddit were They Have Been, They Are, They Will Be and No More Geocaching, although there are quite a few more, more so on the second search term.
