I recommend starting on the very last post of page 3 if you want to see a 30 year old NEET melting down but most of the thread is entertaining. Accusations of child porn, mod abuse, shadow councils, etc. For context, LiLLipuTian is the user that they refer to as Airhogs. He's was modded despite doing things in the past like doxxing another user and following them around making fun of them for being fat.

Edit: Traditionally users challenge each other to a 1v1 for a forum ban when they feud but Airhogs is a pussy and is way worse at dota so he refused and offered a 1v1 lasagna cook off. lasagna cook off thread where you can see some of the harassment.
