What's with the greytide lately?

[Ali0en]

So in the past week I've seen 3 instances of grey tide pop up. The first was the round where the pool was closed. The crew stormed the brig and started murdering sec. Next was out of nowhere. A swarm of assistants swarmed the brig and bombed it. An admin had to tell people to stop and I even had to authorize lethal force against the tiders.

What the hell is happening?
