First you need to understand what racism is..

You must have broken some chat rules and thus were banned. It's better to read chat rules properly before participating in chat. I think they banned you from chat and not the site. You making deposit is of no relevance and doesn't makes you a VIP.

If you are reporting about mod behaviour then you need to work out with their owners. Site owners are the ones who can review this mod action and take an action on that mod if necessary but given the screenshots I don't think mod went out of bounds and did something that he shouldn't do. (Just saying on the basis of screenshot produced here though it is still not clear the actions due to which you were banned)
