Appeal for BANNED BY SR

Steam profile: 76561199247872936 (Sony PS2 [SCPH-39001])

Appeal Plea: I am innocent of all listed offenses
Appeal Reason: [Accounts] Friend/Family - My account was abused by a family member or friend

Victim Repayment: No, I committed no fraud or had no direct victims
Previous Appeals: No, this is my first appeal here​

Alternate or Related Accounts:

I personally do not have any accounts that I use for trading, chatting, idling etc. However, I do know that my brother had used my account for selling MvM parts to trade-bots. That strikes me as not scam-worthy, however it could be possible that he used my account to do something bad:
Here's his SR ID block:
| steamname: Mirivoje Pičkogrlić
| steam3ID: [U:1:247105993]
| steamID32: STEAM_0:1:123552996
| steamID64: https://steamcommunity.com/profiles/76561198207371721
| customURL: https://steamcommunity.com/id/BatOwen
| steamrep: https://steamrep.com/profiles/76561198207371721

Also, the "Additional Info from Administrators" on my SteamRep profile says that he is a alternate account of mine/ that I'm an alternate account of his. Regardless, this isn't true as he hasn't asked me to use my account to do anything trading related. I've even seen him starting to trade again.​

Appeal description:

Okay, so i've been banned on SR. However, I'm sure it has to be a mistake.
I found out that I was banned when I checked my backpack.tf to see if a shotgun skin I put up for sale yesterday was sold. That is when I realized that I had been banned.
I'm not sure why, but I'm getting this nagging sense that my brother has something to do with this, as I described in the "Alternate or Related Accounts" section. Even the shotgun I had listed received no buyers, so I was probably banned because I am a suspected accomplice, or something along those lines?
Again, I state that I had nothing to do with any of this. It seems really sketchy that I just get banned out of nowhere. Please, do something about this.​
