Everybody is always saying to churn by sweeping the coin. Makes sense, works neatly to keep coins apart.
But my thinking is when sweeping your tx only has 1 output. As most transactions have at least a second output for change, doesn't this make a sweep tx look like a high probability churn in the blockchain?
All transactions have at least two, so transactions with change will have 3.
or
A second bogus output is added only if needed to shield 1 output transactions from standing out.
