What I would like to see discussed with regard to online forums would be to expose and denounce the hypocrisy of forum operators when it comes to subliminal product advertising.
I still remember one particularly hypocritical candidate whose entire e-drum forum is based on his own product and who forbade me from talking about my developments on his forum (as if I were even a fraction as commercial as he is LOL). This was supposedly unauthorized advertising. The names and products of the major manufacturers and suppliers were and are mentioned in almost every thread and post in that forum and are a topic of discussion—he has no problem with that virtually ubiquitous advertising. And subliminal product advertising by people who are acceptable to such forum operators also remains and is not deleted; all others are banned. This double standard, which is virtually always present in such forums, is never discussed, and forum users and also independent specialist journalism could change that.
