I would personally like to see another column with a "worst case scenario" for each casino. E.g. if you fail to identify yourself, what would happen? Do they seize your funds, refund you the whole amount & close your account, or refund your deposit only?
May be a bit hard to find that info, perhaps look at T&Cs?
The T&C's would probably always return that the casino will confiscate funds in the worst case scenario. It is probably worth verifying that across all T&C's for each one and adding this information though.
To accurately know the worst case scenario how you have described though, would only be from experience of multiple users. Consistent results would give a somewhat definitive answer. Inconsistent results would give you a worst case but would require more information as to why it varied. I could elaborate on the process but to cut a long post short - it would require an almost impossible amount of time and manpower to be able to do this for every casino and to post accurate information/keep the information accurate.
