Honestly I think you guys and Mt.Gox should follow flexcoin on this this policy, no links in e-mails.
It will help stop crap like this happening to our clients.
It would help, but most people tend to forget that. Just saying that there won't be any emails with links is not a bullet proof technique.
nothing is every really bullet proof... but at least it's another roadblock... The idea is just to try to protect the end users.
