Not going to defend her but play Devil's Advocate for a second...
We need to remember that there are still different generations of GPs working. Some that I've worked with as well as my own treating ones are of an age where IG isn't actually something that they are all that familiar with, and well they mix in circles that SoMe isn't necessarily the 'done thing'. They have no need to announce to the world what they do each day. Now say a patient is appearing in front of them regularly very teary, completely lost or with extreme low mood, or is a patient that is becoming quite reclusive and hard to check in with, if that patient starts turning up in a slightly more lifted mood, more engaging, etc. and attributes it to having discovered such a social media account that is helping motivate them around the house or in general, I can see scenarios in which a GP may not necessarily push the account on patients, but quietly encourage it if it does seem to be helping without it becoming all-consuming. I struggle to see a scenario in which they genuinely would suggest 'prescribing' cleaning and social media if someone presents with anxiety, however I also know of GPs who sometimes find it easier to say what they think patients want to hear to politely get them out the door and/or brown-nose some patients slightly and pander to an ego. Not all, but some!
Now I don't hate Sophie. I don't know her, and I definitely don't care enough to put that much effort into emotions like that towards her. I discovered her when she was relatively small, genuinely cleaning, etc. I was moving home regularly for work, working stupid hours, hated cleaning, and am disabled, so I thought if I could get some hacks that would make cleaning easier and quicker, great! But as she got bigger, management and brand partnerships came along, I suddenly realised I was being dragged back to the 1950s (being disabled and female, I've worked bloody hard to have my career and work to encourage teens in similar positions to believe they can do the same!). Then all the inconsistencies started being very noticeable, leading me to a Google of something and Tattle appearing confirming what I had noticed. I would have respect for her and what she is doing/has achieved if she could just stand up and own it when she gets it wrong. If she just held her hands up there and explained that the gloves come out because it was prerecorded as she has a young child to care for, cannot guarantee light, etc. If she addressed mistakes and bad hacks she's shared after learning the problems. Now it seems that she is simply using a book to double down on inconsistencies, but potentially creating even more. After the Belle Gibson fiasco, if Penguin haven't fact checked and looked for evidence of trolling versus people raising valid concerns, here and in her DMs, all respect for them has also gone.
I don't dislike her, as I said I have no emotional connection to her as a person. But I cannot blindly ignore the fact that all the inconsistencies, lies and fake life portrayed for IG impacts on so many of her (often vulnerable and/or easily influenced) followers and well how can anyone respect that? If she was genuinely being honest with her following, realistically I doubt many would be here on these threads other than the genuine trolls who are out to hate anyone for their kicks!
