I have to say Blockland is actually getting better, and this is my logic:
There are several facts that I don't think you can deny:
Most long term players are older because they don't get bored so fast, and they find more ways to have fun.
As more players join, a certain part of them are older, and the larger amount is younger.
Older players are often "higher quality".
From this you can conclude:
As time goes on, many new players will come, and a few of those players are "good", and in that time younger players who have played for a little while start to stop playing. So as time goes on, more and more better players are coming into the game, at a faster and faster rate.
It's just that the lower ids have already been croped out to only "good people".
Or you can look at it like this:
I think my ID (2156) is in the lower 15% (give or take) of active ids. Since your problems are with people who are 3,000 id or higher, then your by far outnumbered. It's the whole "You think the whole world is wrong and you are right, are you so sure that it is infact you that are right, instead of the world is right, and you are the one wrong?" senerio.
Any way, your wrong.
