I'm not worried about it. Geez, people think that the Internet (specifically the World Wide Web, which is more precise) is a secure medium for private messages. It's not and it never was. What you post moves from node to node -- there might be seven, eight, twenty, or more nodes between my house and the Mudcat servers, for instance -- and the packets could be read or blocked at any one of the nodes between here and there.

Besides, the ISPs mentioned -- Comcast, etc. -- are NOT the only carriers. Believe this, as difficult as it may be. It is quite possible to purchase, install, and use a private satellite uplink for example. And if worst came to worst, you can go back to text-only -- sure, it's not visually exciting but it does communicate ideas.

Or pick up the phone. Or write a letter....
