Like really, last I checked they were paying 1000 sats, or around 8.5 USD cents at the moment. Max comments per day were 100... In the US 8.8 USD or (100 paid comments) are close to the minimum wage. Even if someone completes so many comments it's only natural that they get the content from not so developed nations.
You need 100 posts to start getting paid, you will be paid for a maximum of 30 posts a day, that is 2.5$ a day.
Of course, I highly doubt that anyone has just one account most are farming them and posting with maybe 5 to 10 a day.
How will they make sure that the posts from these regions are not being paid ? If they only check the IP then they can be deceived by the VPNs. For sure, the spammers are wise enough to use the VPN and keep doing what they are doing or they will start KYC on their forums. This method (KYC) can be more appropriate if they want to stop some specific countries people to get paid.
KYC would even make matters worse for them.
They don't need to implement KYC on the forum, all they have to do is ask for KYC when withdrawing funds from yobit if you have % let's say of your funds coming from the crypto talk campaign. That would curb instantly the number of bot accounts there.
They have added two more countries Philippines and Bangladesh,
People should understand that the guys from yobit are not stupid.
They have not banned countries just because of the spam, they have made calculations before that, looking at their clients for their shitty ICOs.
When they realized that 99% of the people from those countries are there just to posts and don't invest a cents in their scam schemes, of course, they have pulled the plug.
Crypto talk is their tool for making money also, they won't be paying endlessly for something that doenst make them money in return.
