Sophia and Freelance pretty much summed everything up. And really, being vague and keeping people's names anonymous doesn't make the situation any better, it just leads to more speculation and assumptions which is the exact opposite of what we need here.
As the person in question who aired this "dirty laundry" (i.e. posted an update on my Tumblr warning people about someone who had created fake profiles to pretend to be different people and stalked and harassed members of my FC) I really don't know why you didn't just speak to me about it if you wanted some answers. As Freelance said, he didn't give me any personal information. I explained the situation, sent him a list of IP addresses and asked if a specific user was using these IP's so that I might ban them from my website and ensure they stop causing trouble in my FC and cease making my friends uncomfortable. He said yes. That was the extent of the "personal information" that was leaked; a confirmation of something I already suspected but wanted to doublecheck before I started swinging the banhammer.
To rehash what some others have said, I don't know why you didn't message an Admin privately rather than stirring up some panic over something that didn't even turn out to be an issue, and IP addresses (that I gathered on my own, at any rate, and wasn't provided from the RPC) don't really reveal much, if any, information about your or your location. I've been on websites that even list your current IP address on your public profile. It's not really sensitive information, unless you have something to hide.
An additional edit: My initial post on my personal blog that seems to have sparked all this nonsense was a heads up about someone in the community who was harassing my FC and exhibiting stalker-like behavior, as they seemed to target us at random and could easily pick someone else at random now that we have them entirely blocked and removed. My post did not include anything about the RPC or its admins giving away anyone's IP addresses, as that never happened, nor was it in any way shaming the RPC. I'm quite thankful for Freelance's assistance in the matter and I'm sorry this came back to cause issue because someone took the matter out of context.
