Vouche problem

Good day.

I've done a trade with a friend for irl money which he paid in cash. I know him irl. He came to me to pay for the stuff I sold for him, and then I made him to register an account here for a vouche for me. I forgot it is against the rules to send vouche from the same IP to the same IP computer/account. I got banned for about half a month, and now found out I have a 'Trade with caution' line under my name. I did NOT scam anybody, only had this problem.

I've made a big mistake, and I admit it, but would it be possible to get rid of it?

Thanks: DraCam

 

Sorry, denied.
