Just stumbled upon this thread and thought I'd chime in. So, about star 67 meaning – it's a throwback to the good ol' days of phone calls. Back in the day, dialing *67 before a number would block your caller ID, so you could make anonymous calls. Pretty handy if you wanted to prank call your buddies or maybe just didn't want someone knowing it was you on the other end.

Now, about the topic at hand – the question about the Oxwall plugin that blocks fake accounts. I gotta say, that's a pretty nifty feature. Fake accounts can be a real pain in online communities, causing all sorts of mischief. Anything that helps keep those troublemakers at bay is a win in my book. Plus, it's cool to see developers coming up with solutions to common problems like this.
