How to block fake google spider and fake web browser access?

[meteor8488]

Thanks for your suggestion.

My thought is 

1. Is it a robot?  
2. If yes, then does't it have a X_forward_IP?
3. If yes, then deny.

Your method is 
1. Is it a robot?  
2. If yes, then if x_forward_ip the same with realip?
3. If no, then deny.

I think there is no big different...
