The question is not the actual spam. The pattern that seems to be common recently is to sign up as a new member, post a question that seems to be on topic (or a reply to an existing thread) and then come back a few hours later and add a signature with a spam link to the profile, which then shows up below the earlier posts.
We usually simply ban spam users and purge all their posts, but since this question led to a valid discussion that would have been removed, too, I just deleted the signature
The 17-85 IS is not the only EF lens with this kind of issue. The 24-105 L IS (1st gen) also can show flex cable failures, which in that case lead to Err 01 messages when trying to shoot with anything slower than f/4 at focal lenghts above 24mm.
