We are being spammed by an extremely clever and aggressive spambot.
The bot uses several techniques to spoof users but is trying a new one today.
If your email address is your username+yahoo.com or username+gmail.com there’s a good chance the bot will successfully spoof you and bypass moderation.
If you have a username email combination that uses the above formula, it is probably a good idea to change username or use a different email. You’ll be moderated at first but once your first comment is approved it will be back to normal for you.
