Ah, art thieves, my old friends... It's been a while!
My Pokemon Patronus designs are being stolen! I've contacted the sites about removal, but it might help if some more voices report them as unauthorised. Here: viralstyle.com/store/vuthanhdu…
And teechip.com/hponix Do not buy anything from these links! But find their contact pages and complain. I think they're user-submitted, not organised by the site owners, so hopefully bringing the facts to the admins' attentions will be enough.
On the bright side, I've not had anything stolen for a long time, and fell out of watermarking habits. So perhaps it's a positive sign that they're likable enough to steal?
