Безопасен ли microworkers.com?

Great site focused on getting help with small short tasks that you may need a lot of people to do in order to get reliable results. A good example would be to have 100 different people rate the product pictures on your website as "poor", "decent", "good" or "great". From a big sample of votes like that you get a pretty reliable result and you can then improve those pictures that aren't very popular. The cost to get help from a lot of people is very low and its easy to manage lots of people at once. The fact that some people use the site for illegitimate things such as doing fake "likes" etc. is no reflection on the site, just on the users. You know a hammer can be used to damage someones car as well...that doesn't make it a bad tool!
