His posts aren't weak, it just seems like a newbie posting away. Are we going to ban clueless newbies?
In any case, how do you know if your account is temporarly banned, or permanently banned?
Temp bans will state the duration. His posts are pretty poor, but I've seen worse, but we also don't know if those were the sole reason why he was banned. If he was account farming all of his accounts will've got banned along with that one and it could be the best of a bad bunch, but he could've also been sending PM spam or doing something else.
