This is my Geocaching pet peeve. There's nothing worse than a TFTC except maybe "#32 of 65 for the day". Generally, these type logs are from out of towners who are just in it for the numbers. I've thought about deleting logs myself, but like everyone says, it will just make them mad and won't really solve anything. It's not like they are going to change their evil ways and start writing essays.
I had a log deleted once myself. It was a Locationless Cache, back when they were still allowed, for a Confederate Soldier's Grave. I took a picture with my GPS and wrote a little bit about it. A month or so later, I got an email saying my log was deleted. No email from owner explaining why. When I emailed him and asked him why he said the cache page required that I be in the picture with the head stone and my GPS. I tried to explain that it was cold and rainy and even offered to send a picture of myself separately. He was adamant that it was his cache and his rules and he could delete it if he wanted. He also said he's deleted many logs and has been called every name in the book, including Cache Nazi, and that there wasn't anything I could do to phase him.
Needless to say, that left a bitter taste in my mouth. I would much rather live with some thoughtless logs than be anything like that guy. A By-The -Way to this episode was that in between finding that cache and having my log deleted, we found our 500th cache. By him deleting the log, my 500th cache is officially another Locationless rather than something unique. I would hate to have had that happen to my 1000th find.
