Is this member trying to cause trouble?

I see this member recently joined and owns a “competitor” :-

Is he just trying to cause trouble?

I answered him in October and the thread has been quiet since. No worries.
PS - I went in and removed the encrypted address to his site.

Thanks for the help LuvMyTJ
