The worst of the worst, they run promotions and charge the sellers, the sellers do not know, the amount shown that they get is not true, because the buyer can claim the promotion and it is taken off, additionally if you buy, I had 2 items that were the wrong size (claimed as French size but was Italian, which is a totally different size) and one item that didn't really look like the item advertised, on all 3 items I left the Rebelle label that it was checked and found as authentic and as described, all items went into garment bags as I could not return (despite them being wrongly described, the Hamburg scammers really make you pay for stuff while they are totally clueless, they are wannabe models from the ads, woefully inadequate and will lie to you if they ever pick up the phone), my only option was to resell apparently without fees, so 2 of the items (in garment bags and with the Rebelle labels on that they are authentic and as described) they found as not authentic, odd, since they sold them to me as authentic.... I am not sure if they are just stupid, clueless or total and utter scammers....
Btw I see that they are threatening people who do not send with law suits, let them bring it on, under German and EU law they have to show that they made a loss and specify that loss to claim it, they are well, a rather shady outfit, would have been alright with the red light district, as much morals and honesty....
Seriously, stay away from the scam project, the only thing Rebfuckyouover are good for is taking your money and lying to you, making you pay for their promotions and having a bunch of failed models pretending to be experts, don't sell with them, you get screwed over, don't buy you get screwed over.... Hamburg's most sleazy business, makes the harbour look like Grünwald.
Also be aware that they pay some shady review sites (like Trustpilot) to remove bad reviews, how much sleazy can you get?
If you want to socket it to them, make a fake account, sell something cheap but make sure you use not your address and do it via an open WiFi and with a generic email address you never access from home, let them try to sue Frau Niem And, obviously it would be very wrong to use an address for somebody you dislike, I could not possibly encourage that
