I earned $8 from a website that I've already sold

Hi WA,
This is a story about never stopping building, learning, and hustling. It's about learning that it's ok to make mistakes. It's ok to sell your website, and expect the unexpected.
A few months back, I sold a website in the MMO niche that was built with the wrong strategy. It primarily promotes WA, but I barely make anything from it.
I made around $350 from WA commissions + a lil over $200 in ads.
I spent about $1,000 on content.
The site generates traffic, but with very low conversion.
Here's why.
I targeted keywords in the MLM niche.
e.g. 'Is Liyelipmal a scam"

These keywords are easy to rank. And brings hundreds of visitors per month. Yet, getting people who are into MLM to take up affiliate marketing is tough.
I didn't have time to manage and grow this site. And there's a buyer who wanted it for $300.
I sold it.
I made a slight loss but gained great experience.
High traffic doesn't always result in high conversion.
The new owner must have left my affiliate links there. As I made another $8 in referral commission.
Will I build another MMO site in the future?
Probably yes.
But with a different approach.
P.S. I hope the new owner never removes my affiliate links :)
Cheers,
Kenny
