u rack i smack

I have been making a mistake for awhile now. Most of the time when I would find a cache I would not physically sign the log if I didn't have a pen with me or the log was full or too small to write on, thinking I am going to log on my device or computer that" I found it". So Is It common practice for the CO to delete my log for doing this? If they do, I can see if people are logging" I found it" online but not actually finding it or even looking for the cache, but really who would do this?
