BT? As in British Telecom? That's terrific! More customers means more complaints and more bad publicity.
It means you are likely to affect admins who can and will unblock themselves. Would you be happy if your ISP was blocked for a couple of weeks (even suposing the ISP choses to take actionm which it quite well may not)? The number of complaints would be pretty low anyway we may get a lot of readers but editors are far smaller in number. We would be the ones on the reciving end of bad PR for hopelessly over reacting.
