Getting merit just because an artwork is incredibly done is not an issue. IIn fact, they deserved to be recognized and praised by others who were blown away by their work, especially for an artwork that required the integration of a brand and a roobet mascot.
It's no problem

Looking back on the Bitcointalk 10th Anniversary contest, receiving a fuck ton of merit from various members isn't an issue, whether it's from solicitation or organic appreciation. Still, a well-received piece of art is preferable than a shallow and meaningless post that was created out of thin air.
