How are people to know this? Stickers on them, sure, but anyone can attach a sticker saying anything on whatever they like, so how legitimate is that? Can I just toss all kinds of shit on the sidewalk if I attach a sticker first saying that it's cool and other people shouldn't mess with it? If they do mess with it, is that theft or vandalism? Doesn't seem like it ought to be. Seems more like I ought to have a fine coming my way, regardless of what happens to the junk I left lying around or what kinds of words I put on it first.

I'd not have known WTF these were when they showed up in my city, if not for reading HN. They look like a company intentionally littering all over public spaces.
