Coincidentally I recently saw a heavily-commented-upon tweet which looked a bit unbelievable so I searched through the alleged OT's stream to find if it was actually posted by them. It wasn't. Two things arise from that though; firstly that in many ways it ceased to matter - it now had a life of its own and accuracy had ceased to be relevant - and secondly that there was no obvious way to correct everyone else's misunderstanding.
The cartoon about "someone is wrong on the internet and I must tell them" might well be accurate (certainly is for me on occasion!) but there is little-to-nothing which can be done. I believe the similar situation applies with data as, unless the original source promulgates the security as an integral component of the data, it can be separated and lost far too easily.
