Just thought I'd mention something that was being discussed on an embroidery group that I follow over on Facebook.
If you find any patterns on Etsy that you feel violate copyrights, please contact Etsy. Etsy does not tolerate copyright infringement issues and will close down any shop that violates their terms.
There aren't any problems with my designs that I'm aware of at the moment, but there are people using the work of other artists and photographers. They use "auto conversion" software and then sell the computer generated chart as their own work cheating the artists and photographers out of possible income or royalties.
The people who do this seem to think that artists have endless funds to pay attorneys to fight for their copyrights. That's a big time misconception!! Anyone who's had to pay an attorney for anything knows how expensive those services are.
The best thing to do is to contact Etsy about it and let them handle it.
