Yes, freezing assets is impossible as on most "Blockchains".   However, still the same people that used to settle markets on Fairlay currently settle most markets on Bitcoin-Betting.  But once the settlement is finalized - by default after 24h - it is impossible to confiscate funds.

Before that, the on-hold balance concept from Fairlay is also used on Bitcoin Betting. That means that only the biggest win in any event is put on hold for 24h.   It is also possible to opt-out of this by paying some insurance fee. This was further refined with the launch of Bitcoin-Betting. The insurance fee is now dependent on the sport and league.  For example, major events have a very low insurance fee, while small E-sport events have a rather high one.



The assignment of the settler of a certain market is subject to the settings the market creator chooses.   

If you wanted, you could create the very same markets again on the platform with yourself as settler. No one could stop you doing that. The way we handle this case right now is, that a warning is displayed in the App, that the settler of the market is not known / trusted. 




If there is something you don't like about the interface, you can fork the App. It's just a huge Javascript file which you can change as you wish.
