Biglion masters new sources of profit

Hi, Habrauser!
Do you like spam? I think no! And I’m sure that the biglion company’s management also doesn’t like him, but he loves money, so he sells his clients to other coupon clubs so that you can make a profit even with your email! As the saying goes, "... even a wool shred"

Somewhere in the beginning of summer, I registered for biglion out of sheer curiosity. I am registering on most sites by specifying mail in the format of domain.domain zone@myserver.ru. I did the same with biglion. Checked in, looked at his wonderful newsletter every evening, after some time, unsubscribed and forgot. But it was not there! It took 3 months and letters began to come to my wonderful box for biglion from some strange sites. One asked my e-mail and sent to the site with a gorilla in a hat, the second insistently wants me to buy something from them, and both sell coupons.
If I was not registered anywhere in a sober mind and sound memory, then someone gave them this box. And not only mine, because other people complained. Only one answer arises - Biglion leaked the database of inactive users. Or it was hacked. Or both. Although the latter is unlikely.
Yes, I wrote a letter to biglion asking who and how could recognize this box. Two days passed and no answer, no greetings. Perhaps the support service has a huge amount of work and they are busy.

The moral of this fable is that - for registration on sites "out of curiosity" there are free services like asdasd.ru - it is simply and convenient to genius!

PS If someone from the technical support of biglion reads this and says where to click to be deleted from all mailing lists, I’m all for it!

Update:
The wonderful magic of the habr awakened the biglion support service and they say that these letters are spam, and they do not disclose anything to anyone! Interestingly, when they wrote this, they themselves believed in their words?
