It was supposed to be a prize for the whalewash game. When they made enough prizes, they just didn't release it. Then some hackers figured out the code and started making filters which let you buy them. eventually the filter got patched and only a couple of them were bought. most of them are deleted by the mods. if you have one, you should keep it safe because it is extremely rare, and the mods might delete it if they find out that you have one.
