Hey, US folks newly running Mastodon instances: do Future You a *huge* favor, mitigate your potential liability, and register with the copyright office and designate an agent to receive DMCA reports *right now*. https://copyright.gov/dmca-directory/ It costs $6 a year. Use a forwarding phone # and a PO Box or other address you check frequently, not your home address: it will be public. Without this registration, you WILL be held liable for any copyright violation on your instance. I also strongly recommend that if you run an instance, incorporate as a LLC and -- this is the critical part -- take out an umbrella liability insurance policy with coverage of at least $2m per incident and covers attorney costs and fees. (If you have homeowners or renters insurance, and you should, this should be a very cheap rider on the policy. 99% of the time it will be unnecessary and the other 1% it will save your ass completely.)
