For me, personally, from actual, factual real life experience, the greatest gatekeepers are the monkeewrenchs aka MODS on yt.
They have three or more heads and snarl at anyone who doesn’t do what they (mods) want them to do.
Mythology – what was the last of Hercules 12 Labours?
Why did Hercules have TWELVE labours?
What was Cerberus doing – keeping the evil in or the evil out?
Where is the River Styx?
Who was Charon, the Ferryman and why do we NOT pay him?
So much has changed now that we are all online EXPERTS.
Que Sera, Sera.
