Who is the mysteroius everpresent 1 Guest?

[Spectrogram]

Whenever I'm on, it's always me, 2-5 bots and this 1 guest. There is always 1 guest.
Who could this mysterious omnipresent 1 Guest be? Are they even real or are they just another bot?
Is there really always lonesome visitor lurking around in between the hypertexts?
Or is it... something else?

Sometimes, in the past, I've always had an open GE browsertab.
Meanwhile, I have reduced my open tabs, so it's not me anymore.

Cheers!

I think it's a atom.

I'm hoping it's Skydereign, constantly watching the forums from above... Get it? Sky, above... Sky... Ahaha.. No? Alright.
