Welcome Solaris
Yes the copy's been written by a 3rd person (or maybe GBC himself - the style is similar to his blog writings in parts).
I still think it's telling - there's a ton you can read between the lines.
The BC parents have a ton of irrelevant personal fluffery on their bios, and of course TM's has the somewhat disturbing "three years later caught the attention of Century 21 Westside principal Gerard Baden-Clay, who at the time presided over the sale of Tonis block of land at Pullenvale." Shudder.
The receptionist gets a full paragraph, even if it's mostly to say how wonderful the BCs are.
BC senior's bio, strategically, uses a lot of random background info on how wonderful he is (Marriage enhancement facilitator? eeeewww), to lend weight to his backing of the son's business. The same strategy could have easily been used with Allison (eg "after a high flying career as personnel manager for flight centre, in charge of 3000 staff worldwide, ABC now lends her professional expertise and experience to...."), but it wasn't.
There's so much about family dynamics and interpersonal relationships you can read here.
And then there's the fact that this page was pulled around the time A's body was found (does anyone have a date for that? I've only seen the archive, but I do remember people linking to the original page back in thread 1 or 2 then seeing it was missing).
What were they trying to hide by pulling it? At first i thought it was out of respect for Allison, now I think it was to hide the creepy acknowledgement of how a certain person caught someone's attention.
