You may or may not have heard that a user on Redbubble has been using various mlp artists work and reselling them as his own original work.
I have Silent-Kosmos to thank for initially letting me know about this guy's activity and ultimately leading up to the efforts made by those on the reddit to identify the stolen pieces.
You can read more up on what's happened and if your art was used without consent on the REDDIT THREAD.
EDIT: Seems everything worked out, Kyle Rene D's Redbubble account was suspended.
Thanks for all the help you guys!
Howdy there, friend! We're here today to wish you a happy birthday! I'm so excited to do this! Rarity told me how fun it can be! Dash said how important it is for us to greet our friends in the other world! It's an honour! Focus, girls, remember how we practiced it... inhale We wish you all the best on this occasion! May you have lots of happy times and good things come your way! And we wish you'll be able to do your best for yourself too! And, and... And stay in good health and high spirits all the time! And believe in yourself and who you are! An' also we wish you great friendship and to have your nearest an' dearest with you to share in the good and deal with anything bad together! So on behalf of all Equestria we wish you... Happy Birthday! We did it, girls. Now let's all celebrate! Cue the music, Scoots!
