clearly not true because I ran an ipfs daemon before and didn't get any nasty letters.
I got nasty letters during the letterbombing attack on Tor relays. They were nasty letters forwarded by Hetzner from the people who actually wrote them. Pointing Hetzner to the page about the attack made them go away.

Here's one of several emails they've sent me over the years, each one happening right after running "ipfs daemon": https://0x0.st/Kryd.png
There's lots of other easily-searchable accounts of people having the exact same experience:

https://github.com/ipfs/js-ipfs/issues/3982
They send nasty letters with pcap dumps of your "hacking" attempts and it doesn't matter how wrong you think they are.
