I am a new member of BitcointTalk, how should I know which category is the best?
I've never utilized it before!
That would mean that you supposedly understand the project that for some reason you want to promote, but at the same time you don't understand the concept of an online forum, that is, you can't determine in which category to place it? For me, the forum is much easier to understand than most of those projects that spring up every day like mushrooms after the rain, and disappear even faster.
However, if it will comfort you, there are many members, even the highest ranks, who do not know how to choose the correct board for their topics, which is completely incomprehensible to me.
Instead of accusing others of censorship, start with yourself and a completely wrong approach - if you cross the street when the traffic light is red and the police fine you, are you going to say that they are censoring where you can walk and where you can't?
