Blockland has had an obvious decline in its active player base.
Banning, dissuading, or otherwise subverting people from acknowledging this won't make it untrue; it's a toxic, unproductive attitude even supported by Baddy.
And it certainly will kill or diminish many good ideas that could potentially extend this game's lifespan.
I've no doubt a stream of good ideas, encouraged and fostered by community members could make a player increase come to fruition.
