Have I Been Blacklisted?

All they had to do was ask, they didn't have to get all technological on a poor, disabled poet. Pretty much since the beginning of this odyessy that the WATCH has existed I have been sending Dr. Latham, Tom Iaribino, and lately Dr. Wary courtesy copies of the WATCH so they could keep me informed if  I said something out of line or UNTRUE and to date they have never contacted me about any editorial concerns.

Now I am finding my e mails bouncing back with the following message:

 The error that the other server returned was: 550 550 Blocked (state 14).

 BLOCKED! I'VE BEEN BLOCKED. I don't understand.
