Why do some people make fake Ids

Friends,
Why do some people make fake Ids? Is it a sign of low self esteem or childishness or an attitude of cheating?
and why other people accept this even after knowing that the same person has other Ids.
Doston,
Ye bade hi sochne waali baat hai ki kuchh log fake Ids kyun banate hain?
Kya ye nimn aatmik istar athwa bachkaanepan ko darshaata hai athwa ye doosron ko bevkuf banane ke liye kiya jata hai?
Aur usse bhi badi baat ye ki anya log ye jaante hue bhi ki ye person kaun hai aur uski alag alag ids kaun si hain, uska saath dete hain

Kya fark padta hai?

sahi baat kya fark padta hai
