it doesn't appear that we can ban specific IPs, so the other option is to close off anonymous comments, but allow open ID. (i'll check to see if that's an option.) the one thing with this is that some anonymous commenters might not know what open ID is, or not even have a blog/website to sign in with, and just give up. i don't want to make this place an inhospitable environment for genuinely helpful non LJ users, but if the ratio of unhelpful comments is higher than i was thinking, i suppose that's what we'll have to do.
we did implement reCAPTCHA for anon comments, so spambots are stalled, but it appears that LJ's methods are circumventable. (as evidenced by vegan_talk. luckily there's a report spam button if you hover over the usericon of registered spambots. unfortunately anon commentors have no usericon.)
in communities, screened comments are a pain in the asparagus, so that's not a viable option here. (mods aren't alerted to unscreen new comments, and members just don't bother to unscreen. it's too much work for everyone involved.)
if you are a regular commenter that doesn't have an LJ account, we definitely want your opinion too, so please speak up. even if you can't vote, your opinion is still valuable. (also, check out open ID and see if you'd be able to do everything needed if you'd still like to comment in the case that we disable anonymous comments.)
what is your experience with anonymous comments in vegancooking
i've only experienced positive anonnymous comments
i've experienced mostly positive, but the occasional unhelpful annonymous comment
i've experienced enough negative anonnymous comments to be aggravating
