Heres a tutorial for what ppl have been saying with erasing the banlist.
1. Go to C:\Program Files\Blockland\config\server
2. Click on the BANLIST.txt
3. Look for a line that has your name on the right side. (The person who was doing the banning will be on the left, while the person getting banned is on the right)
4. Delete the entire line.
There and also btw this should probably go under help.
