Is someone stealing a threadless design?

I saw this on www.Zazzle.com (make your own products)

Is this the creator making money on the side or is someone stealing the design?

Should I contact threadless?

Comments?

Question......Who's on this site?! Is it mostly mid 20 to mid 30 white artsy, Rockers and nerdy men & women with a light sprinkle of ethnic diversity?

I ask this due to how some critique others works.

Artists seem helpful and insightful. And give tips.

Rockers (goth/drop outs) are those who lack any talent
and think everything is stupid unless it's skulls or on fire.

Then nerdy, who feels like they can be important by over
critique everything and think they know what their talking
about but really don't.

Thoughts?

Hopefully I can submit this.
It's more than you think, a clever play on word sudoku with
a twist.
