I was once thinking like you until I realized that sports discussion is related on sport betting in terms of analysis to make a bet. It’s not necessary that post is all related to bets to classified it as gambling when the discussion can be use as reference for choosing a bet.
I’m not a soccer fan but reading those sports conversations by reputable members commenting in there makes me an idea on deciding my bets and to establish basis for my own analysis. But I agree that most user posting on sports thread is doesn’t intend to discuss gambling but rather on sports alone to meet the signature post quota.
You are right on spot as sports discussions are mainly for the purpose of getting to know the point of view of the people about the match or sports and then can decide on which team to bet.
I usually post the odds too in my discussions and give analysis of whether betting is even favorable or not. Though i still stand on my point that one sport should have one discussion thread.
By the way, I see for Boxing, we have separate threads for most of the matches, which is not right either. Why not discuss all boxing matches in this one thread Boxing Speculation, Odds and Predictions
