In countries where there is no work or it is very poorly paid, this can be a very good source of income. Of course, spam does not require too much effort, but writing in English can also be an interesting form of language learning. I do not agree with it, but I do not claim that there are only bad sides.
Yup, I understand that there are legit posters in CT too. And also, getting paid to post on forums has its own appeal compared to other microjobs are more demanding yet pay peanuts.
At least users can be sure that they will receive payment. It often happens that someone performs some small tasks for many days or even weeks and finally the service turns out to be a scam.
Certainly a long way for Cryptotalk to turn into a source of reliable information, but if thanks to this users and forum owners will be satisfied, I think it is very good for the whole community.
