The only solution is to not use accounts which can be easily tracked back to you, and not post information which can be easily tracked back, either. Which used to be common practice. When and why did this change? With Facebook demanding that people link their offline social circle into its virtual one?

There weren't too many real names on high-period Slashdot, for example.
