I've been organizing the task list for address tagging/clustering tools these days, and the more I look at it, the more terrifying it becomes: Recently, I almost followed a "fund flow profile" to do interaction grouping, planning to categorize several wallets into one group for convenience.

Later, after reviewing the on-chain paths multiple times, I realized that the tags were based on "possibly related" assumptions, and some addresses that had test coins sent by others were mixed in... If I had followed it blindly, I would have been mistaken for being part of the same group by project risk control later on, and I would really be wronged.

To put it simply, address profiling can be referenced, but only as a warning light, not a verdict. Especially recently, with the heated debate over privacy coins and mixing services' compliance boundaries, once the tag system equates "passing through a certain pool" directly with "having issues," ordinary people can easily get caught in the crossfire.
I now insist: only do verifiable actions, review the paths myself, avoid mixing if possible, and accept a few extra costs if needed. That's the way it is for now.
