2013-02-27 is also unambiguous unless you’re aware of a country that uses year day month, is not?

There are several people in the comments saying they have to use 27 Feb 2013 because they work with people all over the world. I’m really confused - what does that solve that 2013-02-13 does not? I know that not every language spells months the English way so “Dec” or “May” aren’t universal. Is there some country that regularly puts year day month that would break using ISO 8601 or RFC 3339?

I’d be curious to see a sorting algorithm that doesn’t handle YYYYY-MM-DD with YYYY-MM-DD properly. If you drop the dashes you still get a proper numeric order. If you sort by component, you still get the proper order. Maybe a string sort wouldn’t? Off the top of my head the languages I’m thinking either put longer strings later, giving us the proper order, or could put 1YYYY- ahead of 1YYY-M so maybe string sorting is the only one that’s out.

I do a lot of con/fair/vendor stuff and support. I have heard (but never done because that’s illegal) that among friends it’s very common to not check that flag to save those friends some headache. It’s also a really good way to get scammed if you do it for strangers on the internet.

I suspect that platforms push it down to the users to reduce their compliance burden. Why make life better for your end users by spending some money when you can just make life more complicated for small businesses by having them own everything even the things they don’t know about?

Not quite. The meme is referencing a new law that targets platforms when the money is sent as a payment. So, for example, if you Venmo your roommate 2k over a year for utilities, your roommate is fine unless you mark it as for a vendor (there’s a little toggle whose exact text I forget). This meme is making that joke.
