I'm thinking, “How do I keep my information out of the hands of centralized database looking for people spreading discontent?”
On a public forum?
A siloed server with good security could lack anonymity, but because the data is not centralized, the feds would have to take a special interest to create an account, and because there would be so many of these instances, it would be a very time consuming process.
Kinda depends how it's hosted. You don't need an account to mine AWS if you can just pick through the backend.
