That's not what Ente told me. While this isn't a clear cut case of a scam, you do appear to be backing out of an auction that you won. That to me is justification for negative trust, not to mention the fact that you and your alts have been suspect from last year.
You don't want to use escrow? Fine. Pay Ente for the auction you bid on and won, and he'll ship the coin out. If not, your rating will get a bit more colorful by tomorrow.
This sounds like blackmail to me. Forcing a person to buy a coin so they can have neg trust remove is pretty shady.
You bought coins in three cases. You contacted the seller with a bid. When your bid was accepted, you refused to pay. For this and additional reasons you received negative reputation.
Now, tell me again, with a straight face, blackmail, forcing, what?

The key word here is "bought"
Sure I made offers for the coin but since when did I already buy it?
I think the key word is actually "auction". When you are making bids in an auction format, it is not an "offer" it is a bid to buy at your communicated price. Try going to your local auction and making "offers" for the items. You are going to get yourself in quite a bit of trouble when you back out of your "offer".
I would suggest you refrain from participating in auctions if all of you offers are not binding until you pay.
