As there is a troll lurking like a dementor in our peaceful wiki, I'm here to announce and address the issue.
Some of the steps that I think might be useful now
Please stay calm. We're doing the best we can
Please don't post anything for a few hours. That let's the troll reply something to your posts
I'll be locking every post now to avoid the issue
I'll lock this post too so that the troll can't reply
You'll find your posts unlocked once the troll is gone
The troll will surely end up in Azkaban. Trust us and please kindly wait
Let's bring this wiki back to it's harmonic state!
