Actually you can get indicted from a message board post
A message board post regarding Mike McQuery seeing something very in appropriate about Jerry Sandusky is what partially broke the case .
That anonymous post led to investigators questioning McQuery which provide a crucial eye witness to arrest Sandusky.
The post itself didn't get anyone in trouble, they found it to be a credible lead, questioned him and then got the ball rolling. The post itself was not used as evidence. At best someone could question someone about what was said. Unless there is evidence nobody gets indicted.
I could say I'm slinging drugs out the wazoo here, like 1 ton a week of heroin. Doesn't mean I'd get indicted unless someone had proof. It's no different than hearing word from the street and following that up to see if it's true or not.
