Most beginners use forums just for money, I think the assumption is correct but I don't expect everyone to generalize to all beginners for money. Sometimes they just don't realize that knowledge is more important than money so it takes time to see the behavior change by itself.
If you see the link which the OP mentioned, you will see that the concerned account only purpose was to earn money.
I have joined Bitcointalk since 2020 start or 2019 End just for the Bounty work no any other reason just to make some Earning for myself haha as you Student dreams.
Well in First time i created account started working then got some money then i thought to Share this work with family consider it another account if you want to make more profits.
When you have only focus on earning, you will never learn. Such greedy people will never anything and will keep repeating the same mistakes over and over again.
