What are you on about? The TF2 Source leak has not revealed any new vulnerabilities, and is not the cause of the bot infestation. Valve's inability to maintain a game, sure, but it isn't related.

I thought it was related, the bots appeared ~3 months after the leak. I'm sure src leak contributed to it.

Yeah it reveals the structs and general logic to talk to the server and allows shimmed clients to be written for it.
