And? You don't like girls who do it? Then don't associate with this type of content creators and their content. (I doubt you don't consume adult content)
You don't like manga tackling this kind of topic? Drop manga that tackles this kind of topic. This chapter isn't even about that, it's about internet illiteracy and how it can get you in a dicey situation.
You already said no one hurts you so what's with hate of the content which I'm confident that you also desire.
There's an influx of adult content creator because there's a lot of demand. Why does society look down on people they desire? Sorry for the rant but I just can't understand why people hate that there are people who supply us with what we want. It's not like we can't avoid this contents. They're behind a paywall so let people enjoy the things they want as long it not hurting anyone nor illegal.
Sorry but, he is kinda right there, especially with people with low self esteem or not getting attention before (like her mom did) doing that and falling into spiral by receiving "praise" from strangers with no self control since it's The Internet.
Oh I knew a bunch, seen a few started off as ecchi to paid content, even got to know one rather personality but got hooked way too much on "drowning in flattering".
Internet is really great, but there's a lot of people with no "breaks" whatsoever that will do their absolute best to satisfy their thirst by manipulating people without care for their future, even bribing to show paid content for a price of doing something more graphic. They get off by it.
