Well, I know *I* was on HPfGU back in the day. That makes me a True Fan, right?
From clairvoyantwank and wank_report:

heidi8 makes a post calling a group of fans "idiots," and mistakenly forgot to lock it. She's leaving it up, though it's edited now. Luckily, anon The Reddd Mousie managed to get a screencap of the original.

So what makes these people idiots? Apparently, they didn't submit a bid for a U.K. con with her organization, HPEF.

And why didn't they? Well, there is the fact that everyone thought Accio was going to have a 2007 con there, and so there wasn't any drive to plan another one until recently. Oh, and also, the beginning of the announcement sent out by HPEF specifically mentioned that they were accepting bids for the mainland United States.

Still, Heidi is convinced that the real problem is that fandom is too fractured these days, or, at the very least, she wants to talk about that fact, because that is totally the issue here, and not any rudeness perceived by people who just don't understand how frustrating it is that there are a lot of Harry Potter sites, and every single fan doesn't visit FAP all of them. Unlike the old days, where "everyone was, at the very least, on the announcements list" of HPfGU.

It's not the biggest wank ever, mostly because, though there are some comments calling her rude, everyone is being generally polite.
