::::: There's a tension between attempting to stop canvassing and not biting new editors. The former is a real problem because canvassing is clearly beneficial to the editor - you can't "uncanvass" people who have received non-neutral notices, while there are few sanctions available to discourage the practice (since a preventative block can't prevent what's already happened). In my experience, most canvassing takes place without any repercussions on the canvasser, possibly because admins feel that a block is not an appropriate response, especially to an experienced editor. In fact this block is the only one that I can recollect specifically for canvassing. Sadly it was enforced on a relative newcomer who actually could be forgiven for not knowing the boundaries when notifying other editors about a debate that they were heavily invested in. It doesn't help the general problem of canvassing, of course, but IMHO you did the right thing in this case.
