I had to ban all Tor exit node IP's from my service because of a single bad actor causing problems for a large group of people on a small service I maintain.

Coincidentally Cloudflare often blocks them as well: https://support.cloudflare.com/hc/en-us/articles/203306930-D...

Honestly, I should probably use Cloudflare but this is a negative-profit venture and it's likely not worth the cost.
