Dropbox: permanent storage upgrade offers on ebay?

Question

Cloud computing

Came across ebay for " dropbox upgrade " for similar offers: "Get permanent +18GB storage for about 5 bucks. All you need is your referral link, no other information.
The offered bonus disk space varies from +18 to +21 GB.
Perhaps this has something to do with the current race of universities?
How do these comrades accrue such a bonus? Is it permanent? And isn't this a divorce?

Answer 1

They register using your referral link, changing the MAC address.
There are scripts for automatic registrations. Discussed on Habré.

Answer 2

There are closer offers, with the same +21 gigabytes. A familiar guy from St. Petersburg pumps for 300 rubles. Unfortunately, I don’t know the mechanism, but, most likely, also registration using a referral link.

Answer 3

Here on Habré there were several articles with a detailed description of how to increase the disk quota for yourself using a referral link. The script normally wound up this business in a few minutes.
