I'm seeing lots of themes that are also available at other theme stores, what safeguards are in place to stop people from selling themes that aren't theirs to sell?
We always do a quick search and cross reference the email, author name, and theme info to make sure everything matches up. It's usually pretty easy to sniff out when someone uploads a theme that isn't theirs.
[Edit] Just modified our homepage text. Hopefully this communicates our value proposition a bit better. Thanks again for pointing this out.
