I was banned for implying that a post in /v/ was viral marketing. (I didn't use >implying.)
For my appeal I made a reasoned argument as to why I had reason to believe that the thread may have been the effort of a viral marketer, and why such a discussion may have been valuable for the board. I felt pretty good about it considering I thought hard about my points and proofread my work, whereas I had seen screenshots of other people's appeals where they just take it as an opportunity to further insult a mod.
My appeal was denied. I bet it was the same butthurt mod that banned me. Saw my appeal and didn't give a shit and just said "why do I care to read this" and let me stay banned. Felt bad, man.
