There are copyright laws for a reason, please respect them. As a true artist we hold a self-respect to a high standard regarding our and other artist artwork. DO NOT EVER take credit for another artist artwork. If you do that…… then call yourself a con-artist.
These type of people you don’t want to work with anyway, so shake it off. What does Jesus say; pick yourself up and dust your sandles off and keep moving. God will acknowledge your honesty and open doors and bless you! Always do the right thing in everything.
