I'm going to close this because it's got off track. If you want to discuss someone else, start another thread.
To be honest, the demo was never the contributing factor in this blacklisting. This is a well-known cheat coder and distributor. He was already banned anyway on his old IP range.
I am 150% certain he's cheating in this demo, synthes, and forgive me not posting a screenshot of his IP. No-one has ever questioned me when I've contributed the IPs for other cheats, or the last octet for a static IP where a server log was unavailable, so I naturally assumed my word on IPs was trusted.
