This will be my final reply on the matter as I do not believe you are operating in good faith. But in case you are:

Firstly, the idea that you "cannot be forced to do something within your job description" is unequivocally false, and a sign of a toxic work environment. She actively requested to not be put in charge of a platform that made her uncomfortable, and the request was denied and she was forced, against her will, to do so. I have never in my life worked at a place where I could not request to be taken off a project or task due to being uncomfortable with it. This is not a point of discussion, this is a categorical fact.

Secondly, it does not matter that she was not public facing on OnlyFans. She, alongside her coworkers, were active public figures on multiple LMG affiliated channels during her employment. And OnlyFans is a platform known to be near exclusively used for sexual gratification, and it is therefore entirely unsurprising that the LMG OnlyFans account received a large amount of sexual advancements, objectification, and harassment of LMG employees. And due to my prior comment, I fully believe a large majority of what was received would have been targeting the women employed at LMG. Therefore, putting one of the main victims of said harassment and objectification in charge of managing it is wholly and entirely unacceptable behavior by the management at LMG.

These are not complex concepts, and are not even all that contemporary anymore. And as such I do not feel there is any real discussion to be had on the matter, there are people more intelligent than I that do a better job expressing these things in more empirical detail. I suggest you seek them out if you need more detail than I have provided here.
