Apologies to anyone who was blocked for 1-2 days by accident. Thank you to those letting me know!
Once in a while, my dragnet protecting the server from actual hackers catches a few good, legit users.
I fixed the "dragnet" and fixed everything retroactive to 2 days ago. So everyone blocked should be able to access the site again now.
Sorry about that! It annoys me more than you, I assure you -- it means extra work to track it down, write scripts, and fix everything. But I can't stop trying to block hackers.
