Super not true. Unless they're actively _impersonating_ a Coast Guard officer and acting overtly in that purported role, there's no crime. Simply having a thing called "coast guard" doesn't run afoul of anything. (18 USC SS 912/913).
It’s DNS so they just have to accept the query and redirect it to a local server that answers for anything and returns the 451 error. However, it’s also worth noting that Cloudflare is a giant MitM proxy who already decrypts everything and retransmits it. No communication with any domain fronted by Cloudflare is secure.
That’s not recidivism, which is the return to committing crimes after release. This is a punishment for bad behavior while inside the jail. It’s a method of behavioral control in real time. I doubt that anyone who gets out of jail is using the argument of, “maybe I’ll have to eat Nutraloaf if I go back to jail” as a factor in choosing to commit or not commit further crimes.
And it also isn’t “dreadfull.” I am very skeptical of taking any advice from a person unable to use basic spell checking before publishing an article. I’m also skeptical of advice from someone who has only recently discovered a possible solution for his very personal problems and feels he should share it with the world. In the 12-step world there are people who only do the first and last steps. They’re called two-steppers. You can look up the steps yourselves, but essentially it translates to, “we admitted we were powerless, that our lives had become unmanageable, and having had a spiritual awakening, we told everyone else how to fix their lives.” There are a lot of steps in between being stuck and becoming unstuck. The author should just quietly repair his life and shelve his egotistical need for external validation.
Syncthing is great, and I use it at home. For a robust multi-user alternative to Dropbox (or *cloud), I can also recommend Seafile. I replaced Dropbox with a self-hosted version of Seafile and have never looked back. Also, for a fantastic mail server solution with a great webmail client, look at Axigen. Their free version is more than enough for a personal server, and you can use Amazon SES for outbound mail to avoid reputation issues. I host mine at Linode and love it. If you have a business need or are larger than the limits of the free version, their license costs are quite reasonable.
