I agree with OP. You guys ask for / require "donations" for certain things, so when the "donation" (payment) is completed, then you need to provide your end of the deal. Isn't that the whole point of this website? Keeping people honest about transactions?
For example, if someone paid me $50 to train their strength to 99, and I took my sweet ass time, and waited a month before I started, I would be perma-banned.
