I have pictures of volcanic ash damage as well as sand ingestion damage (there is a difference) but I'm darn sure in todays environment that the half-experts who troll web sites would take them out of context and spew them throughout the web in order to support their own expertise among the ignorant.
Just once I saw what can happen when one of my photos was taken out of context and ended up on Snopes ... hopefully never again.
