I have a private ebay checker that's super stable, custom neural network solves captchas at 90%, captures all kinds of stuff, cookies, etc. I could never quite find the right way to package it as a paid product and selling accounts isn't worth my time. I can get about 500 accounts a day pretty easily, 1:300 - 1:500 with average leeched combos.
I gave a few people copies and I'm gonna give out maybe 3-5 more, but I'm awarding these to people who can tell me creative ways they use ebay accounts. If I like your hustle you're in.
