#plebchain quick question . If i want to mention someone on a post . Do i @somebody for example like in the dead Bird or how does it work here ?

The problem i see is if i @somebody there will be someone else with the same name . So how does #nostr know who i want to mention ? Hopefully i didnt make it more complicated then it is .
