Nitro boost users

Instead of spending your nitro boost on a server to get extra perks, I think it would be cool if there was a system to nitro boost users / friends, maybe with a much higher cooldown to prevent abuse.

Lets say I have a friend that wants to try out nitro but doesn't want to spend any money, I can nitro boost their account giving them access to nitro classic for 7 days, but my boost has a 14 day cool down to prevent abuse. this lets the friend try out the perks of nitro without spending anything and afterwards they can decide if they want to buy nitro or not.

obviously this is just a concept, if you have any input on cool down period or how long the person gets access to nitro classic please leave it below so we can find the best nitro per cooldown
