At first, I chose this service for a small income, as it has been around for about 5 years and I hadn't heard anything bad about it (except for the low pay, but I didn't expect much for likes). Overall, my expectations were confirmed. You can earn about 10 kopecks for likes on VK, a bit more on Instagram, adding friends costs around 15 kopecks, and subscribing to groups is up to 20. There are plenty of tasks, but you can't complete one task for a like more than seven times, so they run out in about half an hour. In the end, I manage to collect around 30 rubles a day, and about 900 rubles a month, which is quite enough to top up my phone balance. The work takes only 15-20 minutes a day, and new tasks may appear the next day, so there's no point in sitting and monitoring on the same day. If you work with multiple accounts, you can earn significantly more, but I'm not particularly interested in that; I'm fine with this income, especially since it's convenient to work on my phone in the evenings. Overall, the platform is average, I’d give it a four (I lowered the rating only because of the low cost of tasks).
