On one hand, if this was her first release and she didn't see all the rules ahead of time, I kind of feel bad. But yeesh, people get too open about what they post on social media. And DSF *IS* monitoring Facebook/instagram/etc (either directly or through informants). This is a fact. This isn't the first release to void numbers for being sold and won't be the last as long as people keep doing it.
It was nice to meet you, Jacobsen! I'm sorry to hear you pulled a bad number. Did your friend get a good one at least?
Oh, and I should add, the overall quality of this release was really good. I had number 198, and usually by that period a long line would have formed. But at this release, very few people were exchanging while I was there. I personally only had to switch out Vanellope, and that was becasue she had some pinprick/dip/fill issues in the rainbow border of her back wheel. The three exchange pins I saw also had those dips, but nothing you would really notice with a casual glance.
