Are you sure about that?
No, I'm not sure about that (normally I'm careful to avoid speaking in absolutes, and that sentence could definitely use a "probably"). 
I mean, my (badly expressed) point wasn't about clicks-per-link across the entire user base, it was more about the fact that I can easily imagine people (like merit sources) getting legitimately annoyed about the merit-sending interaction getting gummed up with a confirmation dialog. But, I struggle to see the same for the ignore-user interaction. Like I said at the end of that point: I'm open to learning about users that feel that this change would make their lives more difficult in a concrete way (that is, how this change will genuinely affect their honestly-considered, realistic forum habits; not abstract arguments about not liking this change in principle).
I've seen enough posts from people who can no longer view their Ignore list, because it's too long doesn't load before it times out.
Yup, I know.Though, if you read Foxpup's post carefully, you'll see that she's trying to add people in bulk, and is avoiding one-by-one ignoring them using the link we're talking about:
(I could find threads they've posted in and use the Ignore link on their posts, but there's too many of them; it'll take forever to ignore them all individually.)
(I mean, that doesn't speak to the other people with thousands of users on their ignore lists, but, it's interesting.)
As a compromise, how about a popup to Unignore someone? Something like: "You ignored this user for a reason. Think about it, think about why you're doing this to yourself again. You don't want to read these posts, don't do it. Are you sure?". Then, charge a fee to unignore the user. Make it more expensive each time you unignore someone
Haha, yeah. Though, the part I've bolded is actually the problem here. People getting ignored for no reason. 
How about this as a (non-funny) compromise: I'll make it so that if you're holding down a certain key when you click the link, the confirmation will be skipped. (And maybe I can add that in a few other spots, too.)
