You don't nessasarily have to ban them, just don't cater to them. Remove any javascript convieniences that enables their defective-by-design devices and they will be repulsed enough not to bother, either that or design the javascript to be really inconvienient. Can those phones disable CSS? Make the CSS really annoying for phone user agents. These are things that could be done with much less effort than managing bans.
