Facebook apparently deletes what is reported as fake accounts. Apart from the doubtful justification to do so (does it harm anybody? what about this fake cat and bird account nobody could be a fool about?), the method employed does not promote fairness and accountability.
Anybody can denounce the site as fake and to take denounciations at face value is really dangerous. The article at TechDirt rightly points out the absurdity of the policy. But for me, it echoes the behaviours of ISPs when receiving postings about controversial websites: is taking down a website the only solution, especially without notice?
