no type flex - banned 7 days?

Well I was just banned because I had a skype left in my thread used for scamming on this site apparently.

This may sound out of the blue, but I had purchased the Skype account off a forum for marketing purposes (had about 3000 contacts who were all involved in the gaming market), and I know that multiple people owned the skype before-hand, and what has happened, is I used it to get adds on here and increase the contacts slowly and it turns out a previous owner of the skype had it posted here and scammed or something, I am not entirely sure.

What can I do here? I can provide purchase proof, the skypes sale links (multiple from 2013-2015 from what I know), resolved ip's over time being far different not involved with proxies/vpn's and more. Pretty much I can supply anything so that the only evidence of it linking to me would be having that skype in my free service thread. I am hopefully looking to resolve this with someone. Thanks.

Also, why was I only banned for 7 days for this reason..? Is that just a mistake? Because I am assuming if there was conclusive evidence it would be permanent? Idk
