Another possibility: Does your example.com point to something with an ideological or humanitarian goal?

There was a humanitarian charity I've donated to, and I saw people erroneously linking to the wrong URLs when spreading news of it. (Say, `foobar.org` and `boofar.com` when the charity is at `boofar.org`.)

So, I just bought the URLs and had them redirect to the correct URL, before a bad actor could snap them up.
