I have a question...

I have been playng on minecraft gamster skyblock(the one with the lava bucket icon) and got banned for..... AFK?!??!?!

Is that actually a thing or is it a scam

if it actually exists please unban me because my friend told me it was ok when i anounced him the afk fish farm was ready he said it was fine and to calm down because it wont have negative results and to trust him because he was here 4 a long time and never got temp banned

at least temp ban him too for 5 hours because he scammed and pranked me and unban me 

thank you,
