Yes, we did use bits of your design to create our signature campaign but we changed them so that they would not be identical....There is nothing wrong with taking inspiration from designs, in fact big companies do it all of the time.
Taking someone else's code != "taking inspiration from designs". You've stolen it. End of story.Perhaps I should reach out to Mihai and point out the lack of professionalism of those involved in running his bounty campaign? And highlight the reputational risk of letting such people work on the Modex bounty campaign?
Sounds like a threat. You're definitely going in the right direction. 
The rest of the post is garbage or ad hominem.
