… I have things I need to do other than dig on this account. However, keep in mind several things. These names are families. Family incorporated. More similar to clans within Asian cultures. Fronts used by clan members and branches to publish announcements and to coordinate.
It would be nothing for one of these clans to set up businesses of many varieties used as fronts for "family inc."
Follow the Wives. The wives are the historic certainty of heritage. A woman can be unfaithful to her husband, but the maternity of a child is almost never in question. Matriarchal line is more important than the patriarchal line.
"Open secret" discussions cloak in pedantics, Smurf accounts, and 'disembodied' or 'dissoaciated' discussions. For example, I have left messages within breads to friends that match up with social media account messages and also point to forums where things that would interest them can be found… If they use a search engine or I can tell them in person where to look for the other parts of what is being said.
Think about how this can be used with Instagram, YouTube, Twitter, and more classic forums to create a very scattered system of communication where no single point of failure or exposure would net a complete compromise.
In order to decode what this satan chap is discussing or prompting by his posts you will likely need two or three more locations where these people are discussing things. They likely signal each other using symbolism… Not just occult. They might do something like pick a show - act like characters from that show, build a whole 'inside joke'. A fan community with an oddly active and exclusive group of members who seem to always be talking to themselves and largely ignore other fan discussions. This would then be used like a signaling system. Profile pictures, typing patterns, etc can be used to indicate affiliation and identity. Members can even use 'open' accounts that can be used by different people - a sort of mask to be worn as a symbol in and of itself.
They love ritual and theatrics, even the variety that may not be satanic in their behavior (… Jury is still out on that… Q has tools to know, I have weird shit to interpret).
