It's probably quicker and simpler to simply state facts:

A long time ago locals decided to keep Lost City an undocumented area (i.e. no guide ... no magazine reports) ... and that regulars have decided to honor that tradition by no longer posting beta about specific climbs ... although giving out the same information in private messages and emails is acceptable.

In fact, the decision about reporting on Gunks routes went beyond Lost City. Locals back in the 80s proclaimed that there would be no new route reporting anywhere in the Preserve. So if any of you folks think you've put up a new route or variation ... better keep your mouth shut!
