On the topic of posting predictions to the forums, I will post a private message that I sent to two people here (slightly edited).
I have not heard back from either person, even though they've both read it, so my guess is that it did not satisfy either person, even though I took a good deal of my time to put together a thoughtful note. (It always makes me wonder if I should just ignore these issues in the future.)

My slightly edited private message:
There are two places where people normally post predictions.
The preferred place is the predictions board, which has some strict rules about posting times — the cutoff time is one hour before the drawing, and the system enforces the cutoff. There are many benefits to posting on the predictions board, the integrity of the numbers being one of them. Another big benefit is that the predictions are automatically checked by the system after each drawing, and statistics on every person are tallied.
The second place people post predictions is the forums. I don't encourage people to post predictions in the forums, but it is certainly allowed. The problem with posting in the forums is that there are no strict rules and no system controls to ensure people aren't posting numbers after the drawing, etc.
In the forums, some people maintain threads that are specific to certain states, which makes it nice for people trying to find discussion pertaining to one particular state.
The person starting the thread will normally state if they are starting the thread with any particular guidelines that they would ask people to follow. For example, some people start contest threads in which they ask everyone to post one number. If someone posted 10 numbers every time, that's just not nice (poor netiquette), and if they continued doing it even when asked not to, the thread might have to be moderated.
There are no strict rules in place for this kind of thing; I have to moderate the forums based on my sense of the person's intent more than anything else. In other words, if I think the person is doing something to purposely upset the apple cart, I will do something.
Some people don't necessarily post in order to give people numbers to play, in the strict sense. Maybe they just want to document what they actually played, or some other reason.
Posting after the drawing is pretty bad, but posting numbers a few minutes before the drawing can be OK, again depending on the thread and the intent.
To be fair to the opposite point of view, it is also important to be respectful of the way in which people are posting to a thread. If it's pretty clear that everyone is posting in a certain way, it's not real friendly to do something in a different way.
My suggestions?
First, my sympathy level is lower for issues regarding predictions posted to the forums, since I do not recommend it. The best place to post predictions is the predictions board, which completely eliminates these types of issues.
Second, I always recommend being respectful of the flow of any long-running thread, such as the state-by-state threads in the Pick 3 forum. There is no rule about posting predictions just before the drawing, but if others are not doing that I would always include an explanation in my post that says basically, "Sorry for posting so late, I realize there's no time left to play them, but I just wanted to document these numbers that came to me before the drawing."
Third, when calling someone out for posting something that you feel upsets the flow of the thread, I would start by suggesting what the problem is in the least confrontational way possible, and if it doesn't help after one try, contact me. Maybe the person is doing something wrong, maybe they're not. But contacting me earlier can save people from getting in a flame war, and it is hard for people to get along after that happens. Burning bridges is never a good thing.
I hope this has been helpful, and it's taken that way. I tried to explain the type of reasoning I go through when I look at these things.
