I have a long-time enemy at the FReepers. He has chided me over the years because I mask my identity and strive not to reveal personal information. He OTOH, makes grandiose boasts all the time. He recently revealed that one of his kids inadvertently outed him in the meat world. It didn't cause major damage but it unsettled him.
The animus between us is largely one-sided and I didn't tell him "I told you so!" - but I coulda ;'}
I recognize that there are people out there who could, given enough time, track me down in the meat world but it would take some doing. Catch me if you can!
