Lately, the airdrop season has heated up again, and task platforms are becoming more and more meticulous with anti-witchcraft measures. The points system makes farming as competitive as clocking in at a job. I've also been looking into address profiling: tags, clustering, and fund flow analysis all connected, which can indeed reveal some "whether it's the same group of people" hints, but honestly, it's just auxiliary reference, with too much room for false positives. Later, I found that an old account of mine was classified as a "suspected studio" because of frequent cross-chain interactions and the same interaction paths—actually, it's just me being careless and trying out new networks... Now, I prefer to keep track of costs and paths clearly, diversify the rhythm, and avoid making behavior patterns too regular. If it can be explained, I leave evidence; otherwise, I leave it to fate.
