I think they should revamp the comment timer. Because honest users are not in here doing obnoxious things.
I think maybe 3 comments and then timer should start. If you get flagged for ACTUAL spam or harassment you should have a longer and more frequent timer. To prevent the obnoxious activity.
I understand WHY they have it, but it really is a nuisance to us all. I comment a lot. I get into lengthy comment threads with my friends here. It bugs me that I have to stop and wait 3 minutes between every friggen comment sometimes.
