# 27 - For those who like to balance on the edge
Gray promotion methods are a simple, fast and inexpensive way to get subscribers, and sometimes several applications. However, many experts on cmm promotion in social networks neglect them due to several shortcomings:
The ability to get a ban on the social network;
Low or even zero conversion of subscribers into customers;
Reduced page activity indicators (ratio of actions to subscribers), which in turn has a bad effect on ranking and may decrease the coverage among loyal users;
The fall of the brand's reputation (roughly speaking, the KFC profile should not leave a comment under your blurred photo: “it worked out great”).
When should you use gray methods:
For the sale of "talking hamsters" - any services and products that users acquire one-time;
For promotion of individual stocks, products or services (for example, you can consider the option of creating a landing page with your most popular product);
With minimal budgets.
