Ban for looting on BoE

Why I am getting banned for needing on BoE.
First of all my main chars are 6k+ gs and i joined RDF HC to gain some reputation,
after looting I needed on BoE for my low level chars.
Second i didn't joined for items from bosses and instead of appreciating your help , i got banned ??
You cannot bann people for such things , we play this game to have fun and not cancer from stupid kids that didn't won the BoE.
If game masters have any questions or they can explain to me why noone asked me about the situation , but instead im getting 5 day bann ?
I can always start lying about people ninja looting ( that i dont like ).
The system is just wrong..
Remove the bann.
