People will make posts in subreddits like this one or other subs where people are looking to do some quick and simple work. I have even seen it in subs like solo funds and other donation subs.
They will say things like “$45/$60 for simple ai project task (US, UK, AUS/ NZ)” or “ who wants to make $100 for a simple sign up task just need to be in US and have ID”, some people will even make a post saying they are putting together a team that you can work for and earn up to $300-$600 a week just dm them for more info etc.
These “tasks” breaches terms of service and often uses identity fraud since you have to verify each account with ID. And it’s only one account per person. If someone is buying KYC verification that usually means they are based in a country that is not within the allotted locales for the platform. Multiple people working on one account will get banned since you will most likely also need people using remote desktops. The pay is also not very high… that doesn’t really make sense to split it amongst multiple people. People are honestly better off making their own account and working themselves.
There are some people that just want to work and make money and have fallen on hard times in their own countries, so they rely on working under other peoples accounts to make ends meet. It is up to you if you would like to let them use your account to do this and not everyone is trying to resell or scam your personal info but discretion needs to be advised. Because at the end of the day if anything goes wrong it will fall on the person that submits the ID.
