There is a bandwidth limitation, but it can not be consulted, my suggestion is to enable some parameter that I can know if any link is being downloaded very often and getting close to burst my quota.
Offering account upgrade or then destroying the link.
If it is easier to send an e-mail with the remaining percentage, it would also be good. (Your daily quota reached 70% of use! Warn 3 times 70% 90% 95%)
Help us love Dropbox even more.
