Map Hogging and annoyed

So i just ran across the map which took some time to get some brimstone and when i got there i couldnt place my horse or bed roll anywhere. A clan on an official server has put blocks nearly everywhere covering at least 2 blocks on the map.

Is there anyway to report this as the brimstone isn’t respawning

I’ve just replied to another person:

I’m afraid its not a ban able offence… but it really is annoying and I consider this as griefing too…

1 tip, you can set the horse on wait command, just be sure you don’t go too far or at least walk nearby every 10 minutes or it returns to the last guarding location.
