He blackmailed me and saying I blackmailing him. Well, I didnt discuss this issue with him in private message, but instead I did that openly on his thread so people can decide if he is plagiarizing my design or not. I told him that I wont process this issue further because he said he knows Modex team personally. But they confirming that they dont know this guy so I can take serious action. He just showing another unprofessional behaviour by blackmailing me instead of admitting his mistake and apologize to me If you think signature design is just a small and not important thing so you dont respect the designers and their design, then this forum is not for you.
