The service really works. This is evident from the VK statistics: unique visitors, views, and friend requests increase after using it. It even brings more benefits than traditional advertising, which costs significantly more money with minimal results. For example, with this service, I managed to reduce the cost of acquiring a user to 5-10 rubles, and these users are genuinely interested in my product, which helps convert many into buyers. Using the service does not lead to blocking by VK, but I try to keep the activity below the recommended level to avoid resembling spam. It's better to reach a slightly smaller audience while keeping the account safe. Other than that, there are no special recommendations for use: if the page has quality content, the results will be positive. If there is no content, then there’s no point in attracting people for no reason.
