Can you track someone who airdropped you?

Can you please explain to me how it is possible to track someone who has airdropped me? I'm curious about the technicalities involved in tracing the sender's identity. Does the airdrop process itself leave any trails or markers that can be traced back to the originator? And if so, how does this work? I'm particularly interested in understanding the privacy implications of this, given the anonymous nature of cryptocurrencies. Is it feasible for the average user to conduct such a trace, or does it require specialized knowledge and tools? Thank you for shedding some light on this matter.
