Most probably know the tells of a fake dom/domme, but what would count as the sign of a fake brat?

Is everything allowed? Should the joker card: 'sorry, I'm a brat always be accepted'?

insert brats giggling here

Obv the standard OnlyFans clickbaits we see here are 'fake' but in some way they are are more authentic to me than others.

bratting is an act for them. They can turn it off/on and are fully conscious of it. The push-pull dynamic is very fun and attracting to me if intentional. If not intentional, very much not.

Google turned up nothing, as if the term 'fake brat' was new. As if every dom/domme leaving a sub because it was too much to handle 'is always wrong'.

Let's say a dom lost his longterm brat and is now looking for someone to live his happy kinky life again. What should she / he look out for?
