Maybe fans of font awesome? I backed their first kickstarters a few years ago and got notified about this one now. Possible that enough prior backers were interested enough by the pitch to feed the new one.

And about pausing the kickstarter: only makes sense if the initial goal wasnt the real goal. A successful kickstarter raises more overall money when users jump onboard the successful campaign, so you ask for less than you need to get more than if you asked for how much you really need. Pretty common.
