I set up a site around 20 years ago - now on https://whatisbifidusregularis.org/ - and got threatened with a lawsuit by Dannon / Danone. I had to give them the first domain because it was a trademark (but not before I'd set up a 301 redirect and let Google catch up with the change). That was in more innocent pre-DCMA times when corporations wouldn't really know how to contact an ISP and get something banned without getting lawyers involved. I enjoyed a realtively long email correspondence with what I hope was a very expensive lawyer from Danone.

Edit: I set up the site on bifidusdigestivum.com after getting too irritated by adverts where they talked about their amazing bacteria "Bifidus Digesivum", which was just so ridiculous I found out as much as I could about it and wrote about it in as SEO-friendly a way as possible so anyone searching for it found my site. It's had something like 1.5m views since then, and still gets 400-500 visits a month. Not huge in the grand scheme of things, but it still gives me a chuckle every now and then when I remember it.
