So basically, all you did was change a color on the CSS from the original theme and replaced the logo with Instagram's logo. You're not even allowed to use their trademark, it's against their terms. Same deal with your "Tumblr" theme, so I don't know why CodeCanyon approve of this... http://instagram.com/legal/terms/ Read ---> Rights: #6
I personally do not use the mark, the buyer has the responsibility to change it or not
So you are not "personally" using the mark to sell your product on CodeCanyon? You know... profit from their trademark. You should learn more on how these marks can be used. The way you used it is against their terms.
Pre sale question ... Is this theme working with new version as of today?
This is such a rip off, even i could make something just like this, and i agree with Indalab, this is a total rip of there trademark and Code Canyon need to block your account and kick you off this website.
Good Luck with sales
