Is it perhaps time to put some sort of captcha or something on the web
interface for this NG? The signal-to-noise ratio's kinda been getting
dragged down by the spambots.
One possibility would be Recaptcha: It should be easy to add, and it
even works without JS these days.
Or, what I find works surprisingly well, and is even easier for users,
is a strategy I picked up from pmwiki:
Just add a textbox labeled "To prove you're not a spambot, enter the
word '[any word at all]' here:" Doesn't matter what the word is, and it
doesn't even need to be randomly chosen. Just pick any one word and
stick with it (and verify it of course). Also toss in some auto-updated
IP filtering based on the publicly published and maintained IP
blacklists, and spam should plummet to near-nothing.
