I'm guessing you mean the $300k buyer? If instead you mean the new $10k buyer then only time will tell.
For the $300k buyer, no they probably made a lot overall.
Doing the math... over approximately 9 years the $300k buyer had an active website, they would have to have made only about $92/day to payoff their investment. Based on the amount of traffic they likely received over that 9 years, I'd say they averaged way way more than $92/day especially in the early years.
$300,000/(365*9 years) = $91.33/day
This of course is a wild guess, but in this case I feel confident that they made their investment back pretty quickly and then any income generated would be profit minus maintenance costs.
