Adult content in general has a lot of controversial stigma to it, that will not change. Anything with controversy usually makes some big waves. The coin name, surely doesn't give anyone a false perception of what its used for though.
There will always be things to mention, I'm sure if the coin was titled, "(insert any other name here)-coin" it would be looked at as false advertising.
At the very least, the bottom line here is, no one can ever say we are false advertising with the coin's name.
WKC is here, and we're all pumped about it.
