When it comes to micro task websites, what I've seen is that the key to success lies in finding the right balance between price and quality of work. RapidWorkers and ySense are decent options for cheap social tasks, and I've noticed they perform noticeably better than some of the other platforms out there. Picoworkers is another one that's worth considering, as it offers a wide range of tasks and relatively low prices. For Telegram and Twitter tasks specifically, Gaintask might be worth looking into, as some people have reported positive experiences with it. It's also worth noting that MTurk can be a good option, but the restrictions and enforcement can be a bit stricter than some of the other platforms. Overall, it's all about testing and finding what works best for your specific needs.
