Believe it or not but using feedback/reports will get you a much quicker respond instead of personal pm. Some admins will be busy handling one issue while another admin can act to the feedback/reports.
It's there for a reason use it.
We like to deal with issues not become friends or chit chat.
Honestly players believe that chit chatting with a admin means it's doing something for the community it's not, they didn't hire admins for that.
