If his friend is back spamming various threads and boards then it is highly probable he will not be shown much sympathy if he gets banned again. Maybe the next one will be a permanent ban or a signature ban but he will have nobody but himself to blame.
'Your friend' is back and spamming bounty links around the forum again.
I am not quite aware what the reason for the ban was (most likely spamming), but you friend should be more careful, to avoid subsequent temporary bans and maybe a permanent one.
