Hmm, well for us our staff structure is very different. Some how our user base is polite and welcoming for the post part, and I get one or two spam posts a week.

I won't us our names for the staff accounts, but here goes

1) We have a core team of Administrators who over see the website in terms of community issues (dramarama), staffing issues (hiring/firing/disputes/guides), creative development (content development I guess) In the past this has numbered 9 individuals. Currently it is 4. Including me.
1a) I am an unofficial leader in all areas, and I am the technical guru. Which is pretty funny to me sometimes. I work along side the site owner, who has been away for approximately 14 months.

2) We have 'Community Advisors'. They welcome new users via PM, and in the welcome forum, answer questions, and pounce on spammers and so on in the 'discussion areas'. In the past we have had...5....it generally sticks around that number

3) We have 'forum overseers and content creators'. They are charged with oversight with particular forums, and put up and develop content for those forums within a particular theme. When there is spam they ban the spammer, and flag the post for removal to the trash bin.
In the past we have had 35 of these. currently we have 16

4) They have assistants, who....assist them. They have no moderative abilities, but have an official capacity and duties in terms of replying to certain types of threads.
At one time we have 125 of these. Now we have around 25, if that.

5) We have 'scholars' community members who spend a lot of time creating content in a development area that covers all themes.
There are about 9 of these.

With ratio...erm...I don't know, our core user base is currently very small, but in the past has numbered around 500 people connecting at once. Which is when we had the staff numbers above. I hope that helps!
