A similar thing to the low activity in the gambling section, at least in comparison with Btt, where gambling is the most active part, and 95% of the campaign signatures are from that sector.
I think we have to take into account, as we already know, that here the number of users is not the same as in BTT, so it is normal that here there is also less participation in what (maybe) should be the most active board, compared to BTT.
I am not sure what can be significantly improved if a certain local board does not have enough users.
It's possible that the forum token plays an important role in this, such as incentivizing teleported users to participate in local boards. I don't think it's easy to organize, but we should definitely do something about it.
