My wife's pregnant, I'm taking lots of 'Whoa, look at that belly' pictures, which are automatically synced with my Dropbox account. Nudity everywhere. ;-)
I expect I'm having nude pictures of my son in about a month and a half.
Ignoring that I just made fun of all these 'nude is evil' rules: Why should Dropbox look at my data, at all? If I ever get a confirmation that they so much as access it for purposes other than backing it up/restoring it or on my direct request (through the client apps/web ui or whatever) I'm going to leave them for good. They provide storage, not more. And storage attributes (bytes stored) is all they should care about.
"Don’t publish sexually explicit images or videos, such as those with nudity or graphic sex acts. Writing about adult topics is permitted as long as they aren't accompanied by sexually explicit images or videos, or any material that promotes or depicts unlawful or inappropriate sexual acts with children or animals. Additionally, we don't allow content that drives traffic to commercial pornography."
Dropbox TOS don't seem to specifically mention it, they're Acceptable Use Policy notes that "unlawfully pornographic" and "indecent" material is not allowed:
"You agree not to misuse the Dropbox services. For example, you must not, and must not attempt to, use the services to do the following things....publish or share materials that are unlawfully pornographic or indecent, or that advocate bigotry, religious, racial or ethnic hatred;"
Well publish is a totally different thing, i have no problem with that as long private shares are excluded. I am not thrilled to publish my Porn Folder to the public anyway (and yeah, i admit i have one).
Interesting would be if they scan anything unpublished.
This prohibits publishing "Violence", "Hate speech" and "Sexually explicit material", amongst other things.
I'd guess it was written with more public publishing in mind, so it's not clear whether it's intended to include purely personal content on Google Drive.
Sounds like Dropbox have the best terms. In particular I like how they allow publishing lawful pornography, while SkyDrive doesn't even allow private nudity! A world of difference!
