Purchased Make Money Online Program?

I will sometimes upgrade an account when I'm confident the site is not a scam. Those that I upgrade in, have to show that the upgrade is well worth the investment. I've invested money in traffic exchanges because referrals are upgrading and I can earn a higher % on their upgrades (I earned 10% as a free member, now I earn 50% upgraded) One member upgraded today, and instead of making $5, I made $25 on the upgrade...that's more than 3 months were of fees to keep me upgraded, plus I'm earning more money from my surfing there. If it makes sense, why not upgrade?
