Yes, Those who do this want to promote their projects quickly by marketing them, but the marketing systems are different in this forum, so they cannot stay here for a long time. Other projects running on the forum for a long time are extensive projects with no problem marketing to several sectors. Due to this, they continue to promote this forum for a long time, which increases the visibility of their project.
In as much as we know that promoting a brand here to get more players in their platform is important, I think project team should other understand that most people here are also looking at how trusted some platform can be, there are some gambling platforms that has been in Bitcoin for a long-term those platforms has build reputation and trust meaning that no player will want to think twice to make use of those platforms because of how swift they are to resolve users complaints and how long they have been in the business without giving the community any reason to doubt them, just as we know, a brand or project shouldnt expect visibility in a shortwhile, the signature has to be spread a across the forum and it wouldn't be just for few weeks for such to happen, it will take time, thats it is adviseable for brands to have patience while marketing so that they can actually achieve their aim.
