Question regarding negrep calling me a scammer with no proof (?)

[52]

Just logged on Cracked to check the reputation one customer left me, and i see this random dude calling me a scammer and leaving me a negrep.



FYI I've negrepped him as well because of his attitude & unprofessionalism on our discord server. 
I have never actually interacted with him personally, thus possibly making my negrep towards him unjustified as well.
This is really annoying for me as being called a scammer as a designer is a bit  weird i could say

Any quick solutions regarding this issue? Thank you.
