The Pros and Cons of sites like that:
Pros:
1. Gets rid of newbie(s) (yes, good?)
2. Eliminates brainless players (++)
3. Removes unwantted and often times annoying Mass PMers (+*+)
Cons:
1. Forum gets flooded by n00b that was stupid
personally, I think the Pros outweight the Cons
but that is just my opinion.
