Stopped using Dropbox a long time ago. Their constant "marketing" emails were bordering on scammy "Your dropbox is almost full!" etc - I try not to deal with companies that play these games.
That's exactly why I quit using Dropbox. I have TWO pictures in my Dropbox, no way in hell it's almost full. You lie to me in your advertising, you don't get my money, period.
Nope, it was an ad for using Dropbox to scan my tax documents or some shit like that.
I contacted support to ask about disabling future fake notifications, and they tried to claim that malware could be responsible.
I suppose in a way, they're not wrong...
