I can't believe there's no way to ask for support, but here we are. I've been using Dropbox for about 15 years and over the past 5 years, use the public links feature to share small files with my music production colleagues. 5mb or so per file. Today, for some reason, I got an email that I'm causing "excessive traffic" and was emailed a link to get "unbanned". I did it twice but now it says I can't get unbanned. I run my music production company through this service so I'm pretty miffed. Any ideas?
