From the linked article
The manager told us he was “excited” about the event, and was unable to recognise any problems in teaching children about sexuality. He also told us that there had been many complaints received and that he felt those emails were offensive.
So complaints were received but ignored because they were deemed 'offensive'. This does not bode well for the veracity of the library's internal investigation.
He described us and the concerned adults who had emailed as “people like you”, lumping us all into a bigoted category of people whose opinions and concerns should be ignored in the interests of “inclusion and diversity”.
He told us that while some of the adults hosting the event might have a DBS check, it was not something requested by the library before allowing access to children.
We suggested that the library should restrict access to the event to adults only, and were offered assurances that only children accompanied by a parent or guardian would be admitted to the event.
The event was advertised as a family event, for all ages, and included K-pop branding to appeal to young children. It was situated for maximum visibility in the foyer of the library meaning all patrons had to walk past it.
The images in the article show that at least one stall displayed what looks like a purple butt-plug - so it does not appear to simply be prosthetic anatomy as a PP suggested - Prosthetic anatomy..... pretty sure if I was a gay man I would want to try prepare myself for anal, its nowhere near like a vagina.
I'm not sure what sort of background checks and training that an adult preparing e.g. a 13 year old (part of the target demographic for this event) for anal would need but I am guessing that they would be pretty extensive. Perhaps any sort of background check is unnecessary as random adults who say they want to help children explore their sexuality are clearly beyond reproach.

The whole thing is just one massive red light to me but maybe I'm just a bit old school.
