The number of spammer accounts was so high that I have pretty much nuked all accounts except those I know personally. If you had an account, feel free to sign back up (there is now a captcha on the signup, hopefully that will stem the flow in the future).
Automated signups fortunately rarely influence the site as I have comments set to be moderated unless I authorize a user. If you want to be authorized, simply comment with something sane a few times and I will unblock the moderation.
Moderation does have the downside that it stifles conversation, but the alternative I tried in the past stifled conversation anyway because the amount of spam was 100:1 to real comments.
If anyone has a better solution, let me know.
