The section was added to separate "investor based games" and the more traditional gambling types like dice/cards, etc. Both gambling communities were complaining because they were constantly fighting over the main gambling section, and it just became a bump war. Its not that Bitcointalk supports investor based games in particular, its just that it needed its own section to solve that dispute.

Trashing them all is an option I suppose, but trashing all forms of gambling is also an option. I can't fathom why this discussion comes up every day. If you don't want to gamble, stay out of the gambling section. Trust being unmoderated is a good and bad thing (mostly good in my opinion) people can go around marking whoever they want for whatever reason. Bitcoin mining is a gamble, so maybe I'll give negative trust to anyone involved with Bitcoin mining! If I did that, everyone would just ignore my feedback, and the problem solves itself.

Everything is just someone's point of view. If you are someone who doesn't care about "investor based games" and any of their implications, just ignore cryptodevil's feedback. If you are someone who finds them wrong and don't wish to do business with anyone involved, then heed their warning and don't. Its not really a big deal.
