Remote attestation, with cryptographically-sealed boot chains to verify to the server that you're a human sitting in front of a computer, is coming whether people like it or not. Techies will wail and gnash teeth, but there's probably no other way to have online communities survive.

It will also be necessary to enforce sanctions on people who violate the trust of a community. The stick needs to be equal to the task of driving people toward the carrot.
