How do URL-shortening companies make money?

They take the extra letters and sell them for a profit at the text bazaar…It’s complicated

@SeventhSense funny.

So I’m guessing the answer is, “they don’t”

No, there’s a significant aftermarket for used characters. Some consider it a black market. I would say that’s a good assessment. At least they are not in the red….of course that’s the domain of the editing pre-owned letter market.

The ones I’ve seen all have advertising on them, except the ones that charge for their service.
