Yes and there is an easy way to avoid unneccesary deletion requests which would pretty well end the subjectiveness of a deletion and pretty well the misuse of "OffTopic' as a reason for deletion....less work for ADMIN
What are you talking about? And what is your magical solution to a problem you haven't clearly stated? I don't think tons of people report posts, any more than people whose posts have been deleted request an admin review.
The "misuse" of "off topic" is not a big deal. It's just the default TOS option. I'm sure if an admin is dealing with a contentious board, it's the easiest option.
