Never understood the badmouthing of new project. In case of appearance the reasons not to trust to new project, I just pass in through without any comments. Explanation can be - the payable trolls form competitive projects. Who will spend the time for free, badmouthing any projects?
bad-mouthing a project is not necessary especially to disfigure it in an inappropriate way. things like that will only waste our time, because that doesn't matter. scam project is normal in my opinion, it's just depends on luck and our research.
