there's sites you can go on where people will make you feel as horrible about yourself as possible until you log off because you can't take it anymore. One man streamed his suicide and people were still berating him and insulting him and encouraging him to kill himself. DISGUSTING that they did this.
Your description is a little ambiguous, but I interpreted it as meaning there are
insult-themed sites or forums that have the
stated and forewarned purpose of insulting you until you can't take it. If that interpretation is correct, why would anyone go to one of these sites and volunteer themself for insults if they
weren't both willing and prepared to receive them? And even more bizarrely, why would someone who was suicidal stream their suicide there and choose to receive insults during their last moments? Blaming such a site for making people feel horrible or commit suicide is akin to blaming rope manufacturers for hanging suicides.
If my interpretation is in fact
incorrect, and you are just talking about regular forums where insults and goading members to commit suicide happen, then obviously that is a different matter entirely and is disgraceful behaviour.
