"DF community"

There is no such thing as a Duty Finder community. Your server is your community, and since there is no reputation loss, the anonymity that duty finder provides (in the sense of cross server) people frankly care about other people. Personally I hope to see these people drop after a 2-3 months.

It's a jaded view, but I can say you aren't the only one who is very disappointed in their fellow players found through duty finder. You tend to find more bad apples rather good in duty finder. :|
