I have received an email for the third time saying I have been banned from sharing for exceeding bandwidth limit. I had no idea such a restriction existed. I have a basic Dropbox account, but have built up a capacity of 13.2Gb owing to hardward deals I have bought in the past that has increased my allowance. I have used 8.31Gb of space, so loads of headroom. I only usually share a couple of folders with friends and this has worked continually quite happily for years. These folders are about 1.6Gb. For some reason I am now getting this ban for sharing. I have gone into Dropbox online and removed every old sharing link I can find; it has no effect. I cannot unban the account on the link, just get a message saying 'something's gone wrong. Contact support', which I can't do on the basic plan. Advice please on how to remove the ban and share within the allowance. Thanks!
