I have no idea what OP was banned for, but it was probably well-deserved even though he'd probably have evaded a permaban in any case. I just have a feeling about that.
it's for spamming, posting off-topic or low-quality posts. after checking his BPIP OP already has 11 deleted posts just days after the registration of his account. I wouldn't be surprised if his account is banned again if he continued posting like he did before his account got temporarily banned.
