Not your service, but the way you spoke to your client (Harkorede) was unprofessional. I consider everyone in our pool to be a large family here, and I trust that no one would scam me. If I work for a pool member and he is unable to pay due to financial constraints or whatever, the best thing I can do is grant him an extension or request that the amount be removed from his prize money, freebet, or whatever. You both agreed to conditions in PM, therefore I anticipated conversation to be kept private as well.
If that makes a bad guy than ok, but I learned my lesson.
We could have all requested the free logo, but we didn't because we respect your time and chose to use the paid service to assist one of our own. I never claimed you were a terrible cop for making me free logos. I'm only saying you should give your client more space to payment.
