For those of you, who like me, couldn't remember what a Tardigrade is, they're microscopic animals that live in water and are also known as Water Bears.
All I can think of is that this is some obscure word used to test functionality of their the piece of software that blocks payments based on a keywords contained within. I suppose someone could test out a transaction with obvious blocked keywords like "nazi terrorist child porn" and see if it behaves similarly, but I'm not going to try it.
It would be weird to block those as they are pejorative used only by people who oppose these things. Try "national socialist freedom fighter". I don't know what child porn is called by pedophiles.
