The rules might be clear, but language provides multiple ways to say things.
It's legitimate for mods & admin to have different interpretations of individual posts. 99.9% of posts are a clear decision, but the .1% are right on the line, and differences of opinion are understandable.
I am a longtime mod, and an Admin on a different forum, and have come across posts that were subject to Admin/Mod debate because they straddled the line, and were not clearly a violation. Mods/Admin makes "mistakes" due to these reasons.
"...And thus the confusion. In closing, the Ihub tos rules aren't open to interpretation...."
