I have never had that problem, nor have I personally seen anyone have that problem.

The "you are replying to someone you have no connection to" warning is a good idea. I thought Twitter at one point did something similar. For me, it has nothing to do with any "Reply Guy" phenomenon, but rather countering the weird parasocial thing that happens to make people feel entitled to join conversations they're not a part of as equal (in the conversational sense) peers. You can talk to strangers! But in real life, there is a protocol and a set of norms for doing so. The norms Twitter replaces them with are unworkable and terrible.

I have noticed that some people still take the server affinity thing seriously, that they might work to create bonds with people that happen to be on the same server. I don't think that model is long for the world. I think we're going to end up somewhere similar to Blogger, where most people "run" their own "instances", which are really just tiny managed slices of huge multitenant servers, and the idea of talking mostly to people on "your same instance" will be as archaic as webrings.
