As there are no free money in cryptocurrency, the only goal of such worthless tokens is to scam address owner. Starting from being imitators of original tokens, and ending with redirecting (not directly but through search) to phishing pages. The worst part of it is that blockchain explorer somehow show value of such tokens. For example on one of my addresses there are tokens that are $100 worth, they are traded on dex and their value is around few cents, but if I google where they are traded, search can lead me to anywhere.
