I had lots of api.dropbox.com queries in my 'Top Permitted Domains' list - it was top of the list. I no longer use Dropbox, so I terminated my account and cleaned it from my Ubuntu system. I then blacklisted api.dropbox.com, hoping that that would be the last I see of it. Now it's top of the 'Top Blocked Domains' list with tens of thousands of hits.
How do I stop all this 'noise' from api.dropbox.com, please?
