Haha, no, it's not my site. I simply plugged their receiving addresses in to block explorers for the relevant coins you mentioned (BTC, ETH, and LTC), looking for an incoming transaction made around the same time as your last post for roughly the correct value. Everything on most blockchains is completely public. Knowing an address is all that is needed to look at all transactions involving that address.
I wasn't aware Mozilla were offering a VPN, but on closer inspection it runs on the Mullvad VPN network, which is one of those recommended by privacytools.io. Do they accept bitcoin payments?
Yes, I knew that most crypto transactions were publicly viewable, I just thought it would be a little harder and ambiguous to pick out any specific transaction. I have no idea if they accept crypto, I opted to pay with my AmEx since it will be considered a business expense for my taxes.
As far as the "take a pic" guy, I really didn't think there would be some draconian punishment meted out, I just wanted to let people here see what a board member was willing to do to steal from someone they thought was unaware. While I was at a loss to know how to get the coin back into the wild, I knew better than to pass a pic along. Others might not be so informed or aware. I thought it was important the movers and shakers and the helpful on the board were made aware of a douche in their midst. I know I will make it a point to warn others of "take a pic" douche if I see him on the board.
