What is cryptotalk.org and why is it on everyone's profile? Is it like bitcointalk and does it also have campaigns?
Where have you been why you are asking now, the campaign already ended and they have a campaign here in over two months this is another forum sponsored by Yobit, so far they are becoming very popular among those who wants to earn even a small amount of Bitcoin, you can earn 1000 satoshis here per post up to 30 posts.
This is expected to see since they are not putting some strict rules about spamming and want their forum to get filled with it but I think that's what the owners want since the more spam topic they can get the more attention gain and they actually gain more traffic since they implement their paid per post but it's kinda not appealing to me since it needs a lot of effort to post 100 and you will get only 0.0003 sats for that volume of post daily.
But for OP it's still good if you have extra time and those little amount will get bigger if you save it.
