I'm not able to share Dropbox links for years

So, I have been banned from sharing links from Dropbox for years, I never did get any understanding of why, I never got an email about it and just dug back through to see if I had gotten anything, but no such luck. It gives a message on the site that I did something against the ToS but I have absolutely no idea how or when. This has been years and I never share links enough for it to have mattered until recently now that I'm doing tabletop gaming. Is there anything at all I can do to get this ban removed at all, I don't even know when this started or why.
