Different strategies are pursuing their interests that's why we all need to trade our own research without taking note of false rumors.
And how will we be able to do that?
The reason that a lot of investors earn and be successful is to follow other investors that are much more successful than them. I am not saying that they can't do their own research, they can it is just that it is better also to follow other investors so they can have an idea. Scam or these false rumors are inevitable but with the knowledge that they have and the other investors that can detect these kinds of ploys will be fine.
