One of the best features of Dropbox is its unlimited Cloud storage option but it is being killed because a small set of users is misusing it. Dropbox has revised its storage policy because the unlimited tier is being used for activities such as cryptocurrency mining and storage pooling with strangers.

“Over time, we found a growing number of customers were buying Advanced subscriptions not to run a business or organisation, but instead for purposes like crypto and Chia mining, unrelated individuals pooling storage for personal use cases, or even instances of reselling storage. In recent months, we’ve seen a surge of this behaviour in the wake of other services making similar policy changes. We’ve observed that customers like these frequently consume thousands of times more storage than our genuine business customers, which risks creating an unreliable experience for all of our customers,” Dropbox has said in a blog post.

Now, customers who purchase a Dropbox Advanced plan with three active licenses will receive 15TB of storage space shared by the team — enough space to store about 100 million documents, four million photos or 7,500 hours of HD video. Each additional active license will receive 5TB of storage.

Customers using less than 35TB of storage per license, which is over 99 per cent of Advanced customers, will be able to keep the total amount of storage their team is using at the time they’re notified, plus an additional 5TB credit of pooled storage, for five years at no additional charge to their existing plan.
