I was dugging around in the blockchain yesterday and i came across something ive not ever seen before, it losely ressemled what you could say was a fiing cabinet with drawers its very broad description to be honest.what i call the drawers had its own key, 5 drawers in total and all the keys were together, waiting to be accessed , i took a key and i opened one of the drawers and it contained a files and lots of them and this is why im here really , i wanted to ask why would somebody store what appears to be emails on the blockchain ? Ive not opened any files yet and was curious whether any anons had come across this before ?
