Why does the neg i give to this fag gets deleted

[SignatureSpots]

I am negging @zfzp after he insulted my service with no proof.
He wanted to do a deal and then started wasting my time.
After i asked him why is he wasting my time he blocked me and wiped the chat.
So i negged him for timewaster (no lies there)
Now he is allowed to neg me and trash my service but when i do it gets deleted
Since when is sale trashing with 0 proof even allowed
