Google and Youtube proxies?

I am wondering if Google shares its proxy detection between the google search and youtube?

For example lets say the daily limit before IP is banned is 300 requests.
Can i do 300 requests at G search and 300 at YT with same proxy?
Or i should do 150 at each to stay under the radar?

Hope someone has some light on this..

Noone?

I think the two websites regarding ips policy are interconnected ...

exactly if GOOGLE Blacklist any IP so it should be use under their all service as well
