I think that it is true that the use of short-term promotions on a forum like BTT is completely useless and wrong.
We have seen some company that conduct short advertising and they earn nothing at all here .
because this will take long time before this will have effect .
I think even one year, when the project reminds of itself, when its OP periodically answers questions or posts of users is also not enough for the credibility and real recognition of the project. And accordingly, its use by BTT users. You need at least about 2 years of such advertising for everyone to start treating you seriously.
But this is my observation, I do not presume to claim that it is 100% right.
Like our company(The one we are wearing) there are chances that this will take players but for long term .
maybe there are successful company that still running their campaign up to now.
