I am generally a fan of @guiltyparties. I believe he tries to be fair from the few interactions that I have seen. That being said, I can't see how they could justify blindly downvoting all of your comments and threatening to downvote the whole dapp.
D.buzz adds tremendous value to hive both in development and onboarding users. To me, d.buzz has proven to be more than reasonable in adapting their app to the wants of the community to include payout limits. They onboard lots of new users via hiveonboard. They are good peeps.
