Well you kept that quiet didn't you Dropbox, not so much as a "we are sorry" email.
Well goodbye, a security mess up like that can only be trouble so I'm drop kicking you out of my e-life Dropbox. I'm just glad I didn't keep any thing important or secret on there.
Anyway I've found a much better alternative, SpiderOak. It features 2048 bit end-point encrypted data containers and 256 bit data transfer encryption (yep encryption on the transit of already encrypted data, got to love that) + its more flexible and customisable in how it does things. Have a look for yourself https://spideroak.com/
