Cryptotalk site will have your IP logs so cleaning cookies on your browser has no effect and if you are banned once means you are banned so you can create new one using VPN and get paid from the beginning but they also stopped new registrants so people who got barred has no other way to get paid and I am not sure that still pay per post campaign is still active on cryptotalk.
There are still activities and they are paying people and I read from one post coming from the admin that there will be a signature campaign, it's been discussed months ago but they have not yet launch one, the one that will benefit are those coming from higher rank
They might pay people 'til this day, however the service itself lost any point/meaning to users so can't say anything good about them
moreover there was this story about them being racist, that was last straw for them imo
I don't know what pilosopotasyo meant by "benefit are those coming from high rank" but i think cryptotalk is still paying users for posting and this is why it started banning users based on their location.
Recently i remember a company talking about lunching a signature campaign in cryptotalk forum.
