Someone left me revenge rep on steamtrades, what would I do

I have two such -rep from keids that do not understand the word i do not need

You can't do anything and steamtrades rep seems almost useless to me

Contact support about it, do not rep revenge back as said on the rules.

Find him and kill him. It's the only way.

Contact support (http://www.steamgifts.com/support). But don't expect a reply soon, it can take a few months since they have loads of tickets to answer. The best option is to contact the person and try to resolve between yourselves.

hack his computer
works every time if you are a pro hacker

"Let him burn in his own hellfire."

Fap in their faces to show dominance

You're stuck with it support won't do shaaat.

reps are overrated

Just -rep him back and move on I guess

Only support can do it. Write a support ticket, preferable with any kind of proof attached to it (screenshot of conversation) otherwise it's your word against his. (Although, it's not clear why he -repped you in the first place, even after his "explanation".)

Then be very, very, very patient. Right now Rinarin is the only one with the power to remove those -rep and like every other support member, she has too much on her plate.

It's simple, burn his house :)

Kill him.

my SG street cred > Steam trades rep.
