Has anybody reported it to Kijiji?
They are actually pretty good about people lying.
There are some drug users in my neighborhood that breed small animals to make money for their drugs. What they can't sell, usually lands in rescues/shelters incl. us (via the shelter). I have been inside their place and it's disgusting.
Whenever they pose as rescue I send Kijiji an email and they generally remove the ads. They are generally asking for supplies and "adopt out" animals. They occasionally also look for fancy type of rats e.g. hairless, blues etc.
