How do you spot fake sellers in carousell?

I want to buy a furniture but medyo suspicious lng ako...

1. 5star rating so mukhang ok...

2. Fast response pero hindi daw kanya yung item so pinalipat ako sa ibang app(sa kapatid)

3. Parang bago pa lang fb

4. I ask for video pero wala daw sya currently bahay...will send daw tomorrow...hmm....
