nip-05 makes one unique on the nostr network  ..  easy to remember npub 

wot  score kinda tells you how many people in your network also follow the nip-05 you are following ...  If someone impersonate (pic or name ) your contact , they will still have a different nip-05 but in case you dont remeber the nip-05 address , you can check the wot score to see if your network follows the imposter .. 
makes sense ?
