I have the same observation as above, and I am in NJ.
Calls do go out from time to time, though. Local knowledge is valuable when ACA is developing a new route or a re-route. Lately, more of that seems to be in the staff blogs. Scan them if you like reading that sort of thing. I have had a lot of fun and no little satisfaction as a long-time volunteer here.
Needing users to solve 2 Captchas to post is a bit too paranoid.
It's only for the first two or three posts. CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is one of several techniques we use to block forum spam. Apparently, some spam sites actually employ humans to sign up, register, and post when their bots cannot. I cannot imagine making a few pennies per try that way, but slowing them down is enough to discourage them.
All in all, the techniques blocked 603 probes--most by bots--in the last 24 hours, a typical number. One still slips through every two weeks or so to be dealt with by one of us volunteers. We would be overwhelmed without the automated tools, and you would find this place rather unpleasant.
