Whilst i have no definite knowledge of the workings of Ebay, I do have a fair bit of experience of auctions in another field.
At the beginning of each sale the auctioneer prattles under his breath about terms and conditions being taken as read, and are clearly displayed at the site office at the place of auction. Then in a big clear voice you get told you aren't allowed to undertake anything which may discourage, preclude, prevent, stop, deter, or enter into collusive practices which may hinder the bidding in any way.
I think what you are talking about comes under this.
But hey, if ya get sent to gaol, I'll send a pancake with a file inside. :D
