I have an idea..
Let us create a limit on the number of stupid threads one can make.
Heres how it will work. All threads will automatically include a poll with two options, "Stupid thread" and "Not stupid thread." After about 25 members have voted, threads in which 75% of the votes are for "Stupid Thread" will be declared to be "Stupid Threads."
Everyone will have a limit of three stupid threads a month. Going over this limit will result in a temp ban. Going over six stupid threads in a month...bad things happen.
Its perfect, my friends, perfect!
