I actually used the link Op provided to see how offensive the said post of Soko was but te link was not directly targeting the post. I had to scroll down and there was nothing offensive said by Soko.
But in my mind, I don't think any of us (or I) will even suggest our kids, someone who is known, a close relative or friends who is not adult yet to join the forum.
You will be surprised the kids will find the forum by themselves. This is possible that they may use some bitcoin keywords in their search and they will be redirected here. They will sign up with unknown username and keep interacting with you here

Some people can't even speak in the real life because of shyness, the only place they pour out their mind to say things is on the social media and it really hurt when they are being attacked with offensive words. Some people can bear been attacked but it is not easy with some people endure it.
In different dimensions it may happen. Some could also be people who don't find love and kindness in the real world. They came online for refugee and unfortunately they are bashed here too.
