did a shitty thing, backed out of selling website... am i legally obliged?

Why are you selling your site in the first place? I am not sure if karma applies to IM. You can backed uot from selling your site but I hope that you will still earn in your site by doing so.
 


Having found the auction.

1) no verified google analytics
2) previously auctioned twice before
3) 'earnings' are wildly different in all 3 auctions you've had on the site.

Dude... your auction looks shady as fuck. I'm surprised it reached what it did.
