They make a "generous" offer for Sumolings at a rate of $29 USD per month. I have long suspected that either there is no lawyer at AppSumo, or the one they have is incompetent at their job. There are many honest developers here, but occasionally outright scammers appear—those who are only interested in collecting money—or people with low social standards. And AppSumo seems unable to do anything about them, unable to resolve simple issues that should have been clearly addressed with the other party. I never pay scammers, and I strongly advise you, dear Sumolings, to do the same.
Exclusive for vaizle: If you managed to deceive someone, it doesn't mean that they're stupid — it means they trusted you more than you deserved.
