Yeah, I had exactly that, but in my opinion better, with fullscreen mode on https://flems.io. Right up until hackers found it was a great place to host their phishing sites...
I created a website years ago that let anyone come and just "post" something online anonymously, quick notes or whatever, but have since had to add a registration process and record ip addresses, as the website was overrun by what looked like russian hackers and the dark web in general looking for a place for uh... post links to child... well anyways, took me almost a month to track down all my own website links, as everything was encrypted and growing faster than i could delete it. def sucks to know that even though i took down the means for a place for them to 'conduct business', they will continue to find other websites.
