Naming of boolean column in database table
I would (and do) use "IsVerificationRequired"
I try to add some meaning to my column names so it's obvious (ValueDate, InsertedDateTime, IsActive, HazCheezBurger, ProductName etc). "Isxxxx" implies yes/no for example without thinking and you only have 2 states unlike "ProductName".
Run with the Is variants, or at the very least swap the Require to Requires. Booleans should be phrased as questions. Is, Can, Has, Should, they're all good prefixes for Boolean functions/columns. See 1370840 for more arguments on this
I would choose VerificationRequired, EmailActivationRequired etc.
Database is the snapshot of the state, so the above said column names goes better over the ones you have mentioned in my opinion.
