An email address can be hidden from bots without violating section 508, for instance: feenberg is at nber dot org or some variant won't be picked up by a robot. But is it really practical to treat an email address as a secret, when it will be shared with hundreds of correspondents? I have mostly thought that was hopeless. We do it on our website because we don't want to bother arguing with people. daniel feenberg feenberg@nber.org
