OP had announcements on so many sections he has one on altcoin discussion, altcoin announcement, games and rounds, service announcement, marketplace, if OP keeps doing this and open an announcement on inappropriate section he might get a temp ban.
OP should just concentrate on having one thread where he think he can build supporters and from there build his reputation by keeping the thread updated and addressing all questions and issues.
Launching a signature campaign is good for the platform with the help of a competent manager a month long campaign will do wonder to his campaign
For that people might get confuse to locate them since they don't stay on the section where they supposed to be posted. But if they do the right thing and instead of creating multiple thread on each section they focus it on those suggested above since maybe for that they became well established and gather supporters. But I guess they choose the cheapest way and spam then like to spam their thread that's why they didn't gather much despite of their long existence in this forum.
But I think they don't have enough budget to use for marketing since if they really have that for sure they choose the best option to market their site and possibly earn more organic result on those paid marketing methods they do.
