Without delving into all the good points that were made in my absence, you really have three options when playing in worlds with n00bs.
1. Help them. Offer advice and guide them thru their first experience in HBD(or their 2nd/3rd experience if they still don't get "it").
2. Ignore them. Let someone else help them. After all, it's not really your responsibility to make sure they understand the consequences of their actions.
3. Abuse them. They paid their money to play a game. Let them play and learn from their mistakes.
In my mind, #1 is the best option. Helping them out will make them better owners and won't hurt the world. In fact, it will probably help the world. Better owners = better worlds. #2 isn't too bad. Not everyone who plays the game is an "active" member of the chat/forum. So, even if you are, you're doing nothing different than those who aren't. #3 is the worst. They have their new game and they're excited to get started. They're going to do something. You're taking advantage of their eagerness/ignorance. You've hurt their team, and undoubtedly, the world. Sure, they learn from their mistakes. They also know they've damaged their team and, in the current state of HBD, know damn good and well they can drop this team and pick up another.
My first piece of advice to any n00b who asks is "If you're not sure, don't do it. And, if it's your first season, you're not sure." I've found, while seeking a world I want to make my permanent 3rd world, that a lot of owners with experience, 5-15 seasons, are still learning the basics. Last year, an owner with 6 seasons(IIRC) was shopping an aging stud hitter. His team had been real uneven(50 wins, 70 wins, 50 wins) so I assumed he was learning and was going to rebuild with youth. I inquired, assuming he was seeking prospects. Nope, he wanted BL-level SP. So I think he's got a plan to win. I check his team. It's a 50 win team. Take that hitter out of the line-up and he can't score. Pitching won't matter. I decide he doesn't really understand the game yet and end the talks. Not sure if he dealt the guy but he wins 50 again. Some people don't quite get "it". Taking advantage of them is wrong.
