統計網友活動的python程序。鄰兄拒不跟帖，放在這裏當做存根，須用的請自用

# Author: 書香之家版主 nearby, November 2022
#
# This program allows you to analyze the activities of all the users in a WXC 論壇, for example, 書香之家(sxsj).
# It counts the numbers of 主帖 and 跟帖 respectively for each user.
# The result is printed into a .CSV file. Note, to view the Chinese characters, CSV file is not good.
# So, you can view the result using Notepad or other text editor and then copy/paste the result into an Excel file.

# the second element is the number of 跟帖

# then return False immediately, otherwise, always return True
