Hiring a good marketing professional is indeed a must when promoting a brand like this.
This is true, and it is a good thing that they already have this covered on this forum, getting a reputable manager like LM to manage their promotion on the forum is a good choice because based on the reputation he has had at managing several projects successfully, there is no doubt that this will be any different.
I agree with you. Some sites that employ reputable managers will usually get good public trust and make many people interested in the site. On the other hand, reputable managers like LM certainly will not accept projects carelessly without doing in-depth research to find out whether the project is a scam or not. I believe BetHog has earned a good reputation on the forum because they have a UX and UI that I think is user-friendly.
