The Automatic subscription process has various negative implications

Describe the bug
When a user has 0 subscriptions an automatic process takes place and subscribe the user to 20 accounts.

Context
Apparently, this process was put in place because some accounts randomly would fall to 0 subscription.

The underlying issue
As the project moves forward, we need to understand more our users. The automatic subscription process has several negative implications :

• This automatic subscription process provides a big chunk of our users with a "common" experience as opposed to a tailored one.
• We have a significant part of our userbase that are long-term users, we need to know them better. An hypothesis could be that this part of our userbase is satisfied with the "common" experience. Thus, we are losing those who are not.

Further investigation is needed
It is essential, to find a way to debug the issue of users subscriptions dropping to 0, recreate it and then troubleshoot it. So we can move away from this hack.
