Anyone can get an ID here, and upload anything (within the size limits)
they want to photostash. There's all kinds of Internet blacklists and
whitelists and other similar things that browsers and anti-spam
programs and ad-blockers and stuff use to "stay safe". Photostash
has been "marked" I think...
In the 80's we used to always set up our ftp servers to have "anonymous
ftp" access, whereby arbitrary people could upload arbitrary files. That
never worked out either
