The SEC doesn't solicit information nor does it discuss investigations. Period.
The SEC also does not have the manpower to go after opinion bloggers, especially when those bloggers are most likely living abroad and impossible to indict. The people that run these bear raids are well aware of the law and its limitations. The SEC has pages of information on its web site warning investors of newsletter manipulation. They don't have time to deal with unsophisticated investors crying over a Company's inabilty to effecively wage a counter PR/IR campaign against smear bloggers.
I would guess Joe called the SEC (out of frustration), was directed to someones voice mail, that person returned his call, listened to Joe's complaints and was polite by telling him to send in information. Nothing more, nothing less.
I highly doubt the SEC is going to get involved. If anything bombarding the SEC with complaints is going to get CCME investigated.. not the bloggers.
