Is it legitimate to use dropbox as file storage for my site?

Question

I am approaching the limits of my hosting plan. I doubled it once from 2 to 4 GB and my site (a popular woodworking community in Hebrew) is getting close to using the disk space

Answer 1

As far as I know, Dropbox "Free" is only for private usage. They also have business plans. I would consider to upgrade your existing host for a few more dollars.
