Who are these people?

I'm seeing more and more completely random people around here, people who I don't know at all. I've got no clue where they are coming from or why they are here, but they're freaking me out. See picture and link.

At that link you'll see a lot of people who most likely have never made a single post.

Are these people coming here just to play in the arcade or something?

I just checked what they are all doing (can't believe I didn't think to do that already.) I think all but 3 of them are in the arcade.

And now every single one of them are gone from the list of active members. It's really freaking me out. And we're talking every single one of them is gone within like 15 minutes. The odd thing is, before they came, nobody was here. They all came at once, they all left at once.

You have uncovered a gigantic conspiracy, sir. WW, I demand you let us know what is going on at once.

It seems daft that one person would go through so much trouble to make so many accounts, log them all in at once, and have them all playing games.

Saying that, though, there was that Draco fella a few days ago who had multiple accounts, wasn't there?

The only explaination I could come up with is it's a classroom full of students, most likely in a computer course of some sort, that are playing in their free time and then they all stop at once when the teacher starts teaching, but that's a bit far-fetched.
