#931 introduced confirmed_at on the Comment model so confirmed is no longer required - we can just check if confirmed_at is present instead. We should be able to do the same for Alert and reduce this duplication.

Still relevant.

I also notice the Alert model doesn't have a confirmed_at but only a confirmed field
