New social network - type me a letter

A new attraction for fans of search engines - a specially designed request in Google gives more than 86,000 network printers, access to which was open at the time of Google’s crawl.

I randomly opened several links - according to my feelings, about one out of twenty is currently working. But still there are workers. Maybe at another time of the day there will be more.
What a scope for creativity - imagine the opportunity to send a message to some random printer located somewhere on the planet. Postcard exchange - in the past, give an exchange of printed messages!

But seriously - guys, block access to your networks. According to rumors, some printers have vulnerabilities that allow an attacker to penetrate the local network.
