I just bought a funded coin last week that wasn't removed, but mine get removed.
for what I know, there are people that report some auctions because are in conflicts with some ebay's rules.
ebay sometimes isn't clear and there are "tricks" to follow their regulation.
I have seen something very similar with another digital item, a clash of clans account. I am not able to list mine, each time it is removed.
probably because there are a bunch of users that doesn't want "interruptions" with this business.... and they made this report each time....
