You're on point, getting banned means he cannot be abke to make a post but he can see other things going on the forum and this will show the last time we attempted to check on the account maybe if he has been unbanned or not and his profile will definitely read the last active time despite he's been banned, as regards the OP ban appeal, i don't expect you being a sr member rank not to have been familiar with the forum to the extent of spamming here, now to crown it worst, you got the mind to plagiarize knowing well how newbies got banned easily for doing such without accepting an excuse for being a newbie, now since it's parmanent ban it's a decision for the moderator who banned you to consider lifting it or not and your chances of getting a second chance may be low here, but your efforts and contributions may in another way speak for you if at all you have been doing well before the ban.
