Peculiar behavior and strange posts...
My parents used to do drugs when I was a kid. I know they were addicted to heroin for a while.
I remember one time I woke up and found that my dad had written a whole bunch of stuff all over the fridge, all over the table, and maybe some other places, in black sharpie. I wonder sometimes what he'd have posted on forums if they'd existed back then.
Wackiness and inconsistencies in recollection of things, apparent self-contradictions, things that seem outrageous or like holes in stories/narratives...
And eventually I noticed that other people spoke and behaved in similarly strange ways. And as I got older I began connecting the dots and realizing that the common ground all those people share is having fried their brains with hard drugs.
Retelling the same story with variation of embellishment can be the tell of someone whose story is fabricated and they can't keep it straight -- but is also a tell for an addict who is retelling a basically true story, spun or embellished differently depending on what sort of responses they want to get from a particular retelling. They want to get you to buy into a version of reality that allows them to ask questions that prompt you for the answers they want to hear.
The old forum used to have a search function in which you could easily bring up a list of every thread a certain member started.
I've been reading the forum since 2014 or 2015 or thereabouts and have used that feature fairly extensively in the past for many profiles, including Rob Banks. His story and some of his wackier posts piqued my interest for various reasons, often in a way like: "I used to think somewhat similarly to this... I hope he learns better like I did!"
The thought that he could be a troll has crossed my mind in the past (part of why I read his thread history in the first place), but I'd be pretty surprised at this point. Impressed, even.
To me he seems like someone very genuinely troubled and in the primary mode of seeking comfort when comfort is the last thing he needs.
I was actually quite harsh with him most of the time.
I don't know what he'd have gotten out of trolling for attention from me unless he likes being called out for every detected embellishment/misrepresentation, being called a dumbdumb and a child, having his addiction repeatedly equated to the gayest of faggotries, and being condescended to for any and all addict shenanigans.
I basically told him that I only had enough patience to talk to him and not enough to be nice, and how he has responded to that leads me to believe he is genuine.
Please keep in mind that if I am correct, then his grieving sister could be reading your posts.
Erring on the side of charity when it can be afforded is not weakness or naivety.
