eNom does all kinds of shady shenanigans with domain renewals. There are stories of names going up on their auction block the moment the registration expires (meaning someone has to pay a greatly inflated amount of cash to reclaim the name)
Unlikely. As much as enom sucks I don't think one could misconstrue any of their ineptitude as evil. They do however have the redemption period at inflated prices, but I've never heard of them moving an expired domain to immediate auction.
None of those reference enom directly -- only resellers of enom. That's like saying I bought a widget off amazon & chase paymentech is fraudulent as a result.
