The member posting 呵呵呵 for many many times in a short while last few days has been banned by me for not being allowed to post for 2 weeks (1st warning), if he keeps on breaching that, he would be banned for ever!
We support 言论自由 and 阅读质量. If someone exercises the former but does not consider the latter for others, we could do nothing but give him a warning or take penalty action
