Yes, but not from a vigilante-style moral high ground.

A group of vigilante marathoners who help bring them to justice?

And doxing is dangerous since it's in effect a call for vigilante justice.

It wasn't what I would describe as a "credible legal threat"--they left no name, no physical address, their web site looked like a vigilante operation.
