Surfing brings in a small profit on a virtual machine, and that's great. There are very few tasks available, and they are mostly intended for auto-surfing. If you use several such services, you can earn quite well, especially on autopilot. Therefore, this service can be recommended, but don't expect big earnings. I use these earning methods on a virtual machine because there can be adult content, viruses, and other unpleasant surprises, so I just run it and don't worry. I make about $5-10 a month with 24/7 operation, and with several such services, I can easily cover the cost of VPS rent or internet payment, or both :). I haven't worked as an advertiser and don't see the point in it... someone like me just sets it up and forgets about it, and it seems that's what everyone does. Nevertheless, there is plenty of surfing available.
