A new IP address doesn't permit to write in 2ch in a first accessed day. It can write the next day. When a thread of 2ch is made, the person who make the thread set the number of comments able to be written by one person in one day.
I'm sorry, I made mistakes in writing. I make a revision.
A plan for the problem of troll.
