I'm glad I missed it and even happier they fixed it. Sorry you all had to go through that, happens in cycles, spring tends to be the heavier cycle of spammers and fly by posters (used to run a few forum boards back in the VBulletin days).
Spring season is always the worse season for spam. It's like every spammer, fly by, troll and strange one comes out of hibernation in Spring.
Man I was asleep that day and woke up to a barage of like 30 or more emails from the forum, it wasn't fun. I have set up a separate section in my Gmail now for the forum so it's much better now. However I don't seem to get all the new post emails I use to get which I haven't figured out why exactly.
