Unless you can track the address transaction outside the blockchain like when send his fund to an exchange which you can ask help for exchange to track user identity.
Even if one tracks a users address to the exchange used, it'll be impossible to get the exchange to give out the address owners identity. Exchanges can only give out that info in a case of a high profile crime or hack, for example if it's a case like the famous twitter hack involving prominent individuals like the ex POTUS; so just tracking any address to an exchange will be more or less useless.
