All of these examples are of pretty high-profile and high-value pieces. I wonder how many easier-to-miss mid-value corals get stolen without anyone noticing? I assume the stores don’t have any real inventory system to notice when something is missing. Every time I buy something they just bag it up and give it to me without any record keeping.
It’s still hard for me to wrap my head around someone in our hobby doing this. The motivation, the act of actually reaching into a tank and stuffing the coral in your pocket or bag, and afterwards having it in your tank as a constant reminder of what a scumbag you are vs selling on Craigslist or something...
