GSD is cerberus as portrayed by his hellish emoticon incarnate. Those who see it for what is can respond to the message; us ordinary members think it makes him cute, but the mods know it's a message. This message occurs when the SB becomes active, so we can assume that this is either 2 things: a two dimensional equivalent of a hamster wheel powering the website's infrastructure, or a syphon of the members' life energy. GSD's presence could be meant to spur the centrifugal force of the hypothetical hamster wheel; although, couldn't the mods do this more effectively?
Yes, so we know that GSD's fills an autonomous purpose. The supposition is that he's a syphon or a beacon, but how? GSD's presence isn't due to a centrifugal power source, but a residual energy: our life source. Let's take this analogy for instance: You put coins into an arcade game - the coins pile on a platform - and those coins are emptied and replenished, only except, you don't have a chance of striking gold. The janitor, RSR, take their key of embezzlement, turns the key hole, and cleans out the cache. That is how they syphon our energy.
Back to phase one, we know that GSD appears once the SB calms down or the cache gets full. How can GSD take our coins while we're still giving them to him? Don't take your hands off your change yet - my theory hasn't faultered. GSD's multi-purposed. While he signals the janitorial process, he also create a rift in the time-space continuum through the interaction with the forum members. Of course, the process is painful, so his presence is short lived.
RSR is an interdimensional space ship that syphons our coins (drachmas) from us at that singular moment, so he's Hermes. RSR ride Zeus's lighning bolt, smiting those who commit treasonous acts against the forums; Zeus's Twam.
Hades is Azaxx (Azaxx is a recluse/hermit), and Church is Poseidon. The other mods fill the other roles, and Drizzy is respectably, Athena.
Twinreaper once spoke of an older power - a group of unappreciated members of lore - the lost 343I generation. Those are the titans, and Twinreaper is prometheus. Twinreaper sacrificed himself to educate and wisen the members, incurring a harsh fate by Twam and his subordinates.
Heed my words. INSURRECTION AGAINST THE MODS!!!!
