You can always argue about a post within the thread or report a post
which is better enough for a forum whereas if you only vote for like
or dislike without putting in comments, that does not really help. In that case
the poster remains unaware of the pros and cons of his post in light of
the voter's POV.
For your question about number two, I do not see how my point
cuts through that option as I am not right now questioning the mods
for taking it off as the practice went offguard.
Life is short, have a six pack.
