You're to harsh.. but I agree with your opinion the only problem that these forum has to be solved is all about spam post and replies this is totally not useful to the forum and surely make the traffic a little more large compared to a normal busy forum with no spammers..I don't think we need any promotional videos to gather a large number of communities. We have a lot of members and still, we are facing difficulty in dealing with a substantial amount of spammer every day. If you are going to persist that kind of promotion make sure that the content is all about the discussion in bitcoin and not about earning a pennies just by spamming lol. 
I would agree with this. People that want to learn/discuss/talk about crypto will find this forum themselves. Mass advertising will only serve to bring in more spammers and shitposters who hear about bounties and want to make a quick buck.
Yeah I also agree with that this forum has already been good ever since no need any promotional video or advertisement ... Only those person who wants to learn and contribute in this forum are welcome ... not spammers !
