I'd hoped deviantart would be a bit more aware of what they allowed, then I saw that in the semi finals...
I do have to laugh though given below the semi final shirts (on the page that mentions it), it says:
"A quick note: These entries are the top 50 most voted for, qualified entries. Some top-voted entries have been disqualified because they did not adhere to the rules or contained unlicensed third party content."
Never mind that at least 2 or 3 shirts aren't qualified due to violating the rules, haha
