Lucho poletti may know of others who may have purchased some.

Maybe someone with a lot of Crypto Twitter followers can tweet something about this? 

I actually have a MongoDB dump of all the addresses and orders that were done within the site over the past few years < ~May of this year.... I'm not sure the halving sets are in there, and I don't have Mongo currently setup or the time to deal with it this weekend, but I will publish it (minus any customer info) once I get time. - He gave it to me to try and estimate how many cards were funded and how much BTC was on them. At the time it was a bit under 25 BTC. Once I publish the DB dump you total python geeks might have a blast with it, I'd also like to know how many were peeled after the "incident" etc...

Thanks.
