I remember visiting this website once...
It was called Adopt: Deathnote - L
Here's some stuff I remembered seeing:
Squiby Users are, hereby, advised to follow extreme caution in reporting pets, which they deem either copied or fake. Users should report this only after they have done everything in their power to ensure that the reported pet is either fake or copied otherwise a wrong report may lead to the blockage of the reporting party\'s Squiby Account.
