I just spoke with a member of their customer support team regarding this as I was curios as well. They said they removed the profit/loss information because the stats were not accurate according to him. Data such as rakeback and race wins wasn't reflected apparently. He also said players can contact the support anytime they want to view their records. Not the optimal solution, but that's how it is now.
So they're not going to have stats at all, I wouldn't say just because they're not showing profit/loss stats their are definitely trying to pull something here but I agree with OP that they should be transparent and have some sort of a profit and loss stats for their users to see where they stand in terms of profit once in a while, I certainly prefer to have access to my betting profit statistics at all times even if it is not that accurate instead of having to contact the support to get those stats every single time.
P.S. This topic probably should be moved to "Gambling Discussion" section.
