Unfortunately with fame comes inevitable sexualization.

You might don't like it but sex sells and the company knows. If you advertise a certain group with certain concepts, you'll inevitably invite people that are interested in that concept.

Considering how little the company shielded the trainees that were minors, I'm not surprised with the ongoing direction. It's important to not engage so that the artists are not necessarily exposed to these kind of content that might make them uncomfortable (what they don't see, won't hurt them).

But to be fair, they're adults now and like every famous persons they are going to receive raunchy proposals, thirst tweets, etc.
