特此聲明

I suggest not to block him.  If no one cares his post or reply him, then it would be enough.
It is just my personal view, i joined this forum over three years. In fact, I used another name to participate here long time ago.  My feeling is that if no one has interest or comment on my post, then it is meaningless and I will not have any interest to come back.  Therefore, I have never replied on 奄尖大少's post.
This time, 奄尖大少 is quite success as 版主 opens a thread for him. Right?
Frankly, 版主 can block him directly and does not need to open a topic to discuss him.
From another point of view, it will be good for this forum if many people come back to follow 奄尖大少's "high" quality post.
