Dick Eastman has posted the following article on his blog. This can go in the category of "stupid genealogy crimes" (the "perp" posted the evidence on findagrave) and more sadly, ignorance. Spread the word--don't touch tombstones without knowing what you are doing (see links in article, esp. www.gravestonestudies.org)
and ask permission.

"Here is a sad bit of news: A man is suspected of damaging several
historic graves with a wire brush recently at the New Providence
Presbyterian Church on Stoney Point Road in Surgoinsville, Tennessee. He
apparently used a wire brush to make the engravings on the tombstones
easier to read. Now here is the worst part: he was “cleaning” the
tombstones so that he could take pictures to be posted on
Find-A-Grave.com!
"Aaaarrrggghhh!
"On July 15, church committee member Bill Davidson reported to the
Surgoinsville Police Department that several tombstones had been
“scrubbed” — possibly with a wire brush — causing damage to the old
stones. The dark stain that builds up on tombstones over time was
scrubbed clean in streaks over the engravings, and in some cases the
engravings were rubbed almost smooth — to the point that the words are
no longer legible. Davidson stated that some of the damaged tombstones
date back to the 1700s, and some belong to Civil War veterans.
"The church didn’t give anyone permission to go onto cemetery property and scrub any stones, Davidson added.
"Here is the ironic part: the culprit was easy to find. Police did
some checking on Google and located recently posted photos of the
damaged tombstones at
www.findagrave.com. The culprit’s user name was clearly shown on each photo.
"You can read more about this tragedy in the Kingsport Times-News at

If you are in a cemetery, please do not touch any tombstone, much
less historic ones, unless you know what you are doing. You can find
dozens of articles online that describe what to do and what not to do.

https://www.gravestonestudies.org as an excellent resource although some of the other sites may also be very good."
