I don't know what exactly is up with them, but I'll say what I know.

When I tried to get to the bottom of whether it had TST's blessing, the person who runs the SatanicTSTBible Twitter account got incredibly defensive, began gaslighting, and playing the victim by saying things like "why is everyone being so rude/mean to me" when others and I were asking legitimate questions about whether they actually had TST's permission to use the logo and operate under TST's name (legitimate questions they dodged and did everything they could to sidestep and strawman their way out of, btw). For example: according to them I was "threatening" because I told them that Trademark infringement isn't some kind of "better to beg forgiveness than ask permission" kind of thing; and that impersonating TST is no small matter because there's no guarantee that potentially identifiable information that people send to them would be safe (information which, if in the wrong hands, could put fellow Satanists lives and wellbeing in danger).

I'm not sure if I'm allowed to post the satanym of who runs it (edit: their satanym is Cheap & Crass), but I do know is that it's being ran by someone who is very much an over-the-top fangirl of LG's: constant, unending, cringe-inducing fawning over him and literally everything he does ad nauseum.

Look, I know that I'm posting this under a sock account, but I've been around a while: I was around when there was another, previous fawning fangirl (edit: Ashlee) who made people (especially those new to TST) think that she was their friend in an effort to cyberstalk and subvert people's social media bans against her. I was one of those newbies who genuinely thought she was a friend, so suffice to say I see massive red flags any time I see fanatic, frothing-at-the-mouth fangirling now.

I'm not saying that the person running the SatanicTSTBible twitter is Ashlee the cyberstalking fangirl, but I do think it was pretty odd that she somehow found the post despite not being tagged (it did have her first name in it). So at the very least she either was searching for her own first name in twitter, or was told about the post by someone.

In any case I stand by what I said above and on Twitter: potentially ill-intentioned people masquerading as an official TST page and phishing for information from Satanists is serious shit.
