I've had a DropBox account since the very early days. I've never used it much, but once in a while it was a quick and efficient way of sending a few files across the world. And it was free. Now, every time I use it, I'm bombarded with "Your Dropbox is almost full" / "Upgrade account" messages, and occasionally, despite the few items stored there, it refuses to help on the basis that my account is "full".While it may seem unfair to gripe about a free service, I've cost them very little over the years, and I've recommended them consistently as a good and reliable service. But I've had enough. I'm closing my account, and will recommend them no more.
