Actually no mediators means nobody can intervene between you and Satan. A mediator is someone who is supposed to speak to Satan and give his words to other people as well as speak to Satan for other people and get his response. No mediators means you can have a direct relationship with Satan without anyone speaking on behalf of Satan or to him for you.
But it's true that nobody seeks to meet with others if he's new. It's dangerous to do that. If someone is new he must practice and study on his own. Some experienced people might get a chance to meet with some others who are trusted and experienced and whom he communicates with online. But even in that case it's a totally different thing than saying "hello guys, is there any group I can meet up with?". It's more like a meeting between trusted friends who know eachother online and have been texting themselves.
