So for example, I teach in a school overseas. We have an annual Book Week where we invite a UK author over - they do a week of talks to classes about their writing, an assembly, lunchtime small groups of talented student writers & so on.
We've had some fairly big names & it's always a big event in the calendar.
It's part of my job to book the author, & part of that is liaising with the agency re suitability - someone who wrote gritty YA novels about drugs & teenage sex wouldn't be suitable across the age range however brilliant & inspiring they might be. (It's basically like picking a movie for the family - you can't go above PG or maybe 12, even if some of the family are over 15 & would much rather watch something more adult).
I also always check social media presence, & these authors always have a clean, professional page promoting their books, nice appropriate photos, testimonials from other schools etc.
They might well have another personal page under a pseudonym where they're licking absinthe off a fire breathing can-can dancer's bum, but that's not their official SM 'presence' which can be googled by kids, ffs.
This is not rocket science. It's safeguarding 101.
& if someone doesn't understand this, they obviously don't know the first thing about safeguarding. Regardless of how charming & wholesome their act for children is. It might be fabulous & funny & the kids might absolutely love it.
But they still need to learn about safeguarding standards for working with children, before they go anywhere near them.
