The answer to your question is certainly no, especially at a time when people are increasingly forced to be online, either for work or for fun. But you need to know that people's habits are changing and that things are not the same as they were 10 years ago - today people spend more time on FB, Twitter, Telegram, Viber and similar social networks.

You actually want free advertising which used to be really effective through various forums (I remember someone offering such a service on dozens of forums), but if you want to advertise successfully then you will have to pay for it. Honestly, this is the only way you can reach new customers, and if you have a good product you will make a profit.
