I had the exact same experience and got this mail on Monday. I have once claimed a few codes on the stream (which we are told to do, right?) and even though I lost my depo's & the bonuses, I am getting banned from drops (& rain, given I have exactly since then not received any albeit being an active chatter).
Our Mods (CM's) seem to not be involved, hence chasing them for an answer wont work. However, they should forward this to the relevant department.
We all deposit for the fun, the win and losses. We include the promotions in our calculations. That is what we are offered. So, if someone buys a product that includes a certain benefit, you should get it as it was advised.
Throughout the board, to whomever I speak, everyone seems to be annoyed with the recent promo-politics.
That includes, despite more users, the amount of bonuses being kept the same.
I think it is time for the platform to show that the users are heard.
