No you're right Fleur is James Grant along with people like Cherry Healey, MyPaleSkin etc and her network is StyleHaul.
Gleam is your Zoella, Tanya, every chapman (pixiwoos, Jim... think there's another one), Zoe's brother Thatcher Joe, Louise sprinkle of glitter. Different brands and different circles, target market etc
Most bloggers I know work really damn hard (myself included!) and will declare things. You get really good at spotting paid for/freebie stuff as well. I was surprised a friend of mine was sent sent freebies to "gram" and isn't anything like that. Just a pretty girl with a big following.
YouTube is a different beast entirely. However I love people like Liza Prideaux (had a lovely email exchange with her once) and I've seen so many YTers come and go.
I've had some great freebies myself but I always declare them and for every one I work with there are so many I've said nope too. I've said no to things like power tools, blutack that has the properties of magnets, a chainsaw (!!!) and a weird events. It's still a job though and even though a lot of the time it looks "easy" when you're chasing light around and trying to find a 78th synonym for "on trend" it wears thin.
Thankfully I spend most of my blogging days blogging for other people now, but I still dabble on occasion. You couldn't pay me to be a parent YouTuber though 🙌🏼
