Some background
The nomination phase of the election at Physics.SE started yesterday. When I first visited the nomination page, 7 users had nominated themselves. A few hours later, the number was quite smaller. Digging in the chat transcript, it turns out that two candidates were disqualified because they were suspended within the last year, according to this policy. The disqualification was the result of an automatic script that implements that policy. Nevertheless, both users felt targeted and started ranting in the chat room. I think that, if those users had known this rule in the first place, the election would have been more civil.
So, make this policy more prominent
Running for moderator is an important part of the participation in the community. It shouldn't depend on some obscure meta post. The faq and the nomination page should reflect that, besides the reputation/badges requirement, candidates must have a clean historial.
