Quote from Appeal - Why were you banned? I was not banned, but I was imprisoned in a large cage and told I had to clear it to bedrock to be free. I was punished for placing wool carpet in the shape of a very racially offensive symbol on the ground near another players home.So the player was punished, where as this is you stuck in a hole.
So as you quote, 'i was punished for no answering questions because i was lagging' therefor, maybe you should have logged out and in or inform a staff member... at the time.
Not a staff member here, but I think that with this low fps you won't be able to play Minecraft regularly either even if you were unholed.
