league of legends account process from middlemen

[denysius jr]

What do middlemens do to make sure the LoL account is not susceptible of getting reclaimed afterward ? VERY IMPORTANT : Is he capable of verifying if its the original mail adress (OGE) ? Can i ask additional safety steps for him to do if i'm not sure about something ? Can someone explain to me what does the middlemen exactly do please, i kinda need to understand, like what are the steps he will follow for a league of legends acc specifically ? ty by advance for the answers friends
