Joe,

I did not this that ISP's would edit the packets that customers send
back and forth between each other. I sure hope they don't start doing
this with our e-mail, they'll begin to look like those documents release
from our government, you know the one's with every fifth word blacked
out.

But if the ISP is really dropping characters out of packets, the one
solution would be to use a VPN. That way the ISP can't even tell what
protocol if being passed over the connection. Just as long as they don't
start dropping characters out of the VPN packets.
