Does Ebay actually care?

to my watch list hours after it was listed too keep an eye on it. I didn't truly believe anyone would fall for this, Especially at a BIN of $3600 (to good to be true). Sure enough the bidding started on what were deff. shill bids, so I reported it with the obvious descriptions as to why. I feel bad thinking someone who doesn't know better is going to get burned. Never get a response from ebay, and the few times I've reported something, the bidding just continues. This time over $1000 more than the BIN was.
My question is do they really care? And is time better spent reporting here, as opposed to ebay?
