Posting on YouTube

A while back, after I had posted a few videos on YouTube, I started getting these email messages...

Re: Your Videos
Dave,

I wish that I were able to fully articulate my company here. Due to the fact that we are in direct competition with YouTube there are certain things that I'm not able to say here. I hope you understand.

What I will do however is share with you my mobile number so that you can give me a call 619-573-2810.
Looking forward to your call.
Warm Regards,
Ethan

A bit weird!

I got a few of these messages, and who ever it was, they wanted me to ring a number in North America, cause they wouldn’t reply to email.
