I agree with you, that's not an example of corruption. As a referee, you might naturally go against players that give you a hard time.Sounds nothing like corruption. Bloke doesn’t like another bloke because he doesn’t like him.
Are posters in here corrupt because they don’t like what I say?
It makes him a shit referee, not corrupt.
Corruption is hard to identify and prove. There is bias though, and there certainly is incompetence. If incompetence favours the same clubs over a long time, and discriminates against the same clubs over a long time, then you have to ask if they're is anything more to it.
