Okay:
If the game has little to no good servers online, then please take the initiative to create something that you would consider a 'good server.' It would help the community much more than ranting here.
I'm sorry that you view the loss of RTB as such a negative impact on the game. However, it always was only a modification to the game. It never improved the quality of Blockland itself.
Badspot has said this before, but I'll paraphrase it. Badspot started development on this game around 2005; almost 10 years ago. I'm not sure how old you are, but I'd be surprised if you could even remember 10 years ago accurately. After a while of working on the same project, it just doesn't hold your interest anymore. Badspot does what he can.
On the topic of bugs: please either list them here or PM them to Badspot. He does take initiative on fixing bugs.
