Why would running a full node on amazons service be any problem if its legit? Unless I am missing something?
One of the fundamental ideas behind Bitcoin is decentralization, right? When you start a node at such a service, you aren't really contributing to the decentralization, as more people could run their nodes there which equals centralization. It isn't a big problem, but I would not recommend running nodes there (at least pick less-populated/less-known services if you have to). However, according to
bitnodes21 there aren't that many nodes run at Amazon (at the moment ~160).
Yes, the IPs came from my new node.
Well, they're the same as can be found on my list. The ban-list that I've provided after should effectively ban all of those known IPs.
I've updated my graph once more, and it seems that the problem is gone (for now).
