To summarize it all, I'll say greed is the reason behind all you're trying to say in your thread. Without greed newbies won't engage in this crimes. It's because of the greediness in them that makes them want to steal someone else works to pass it as theirs so they get the accolades and probably the merits reward needed to grow their accounts. If not for the greed, they won't be spamming the forum just to meet up weekly quota for their campaign to get paid. Same thing with greed when it comes to scamming people as well as people who are satisfied with what life has given them won't result ti scamming others if the little they have as well.
To avoid all this problem, one needs to able to control his greed, we all have it in us but how will manage it will determine how successful we'll be both on the forum and off the forum. You have to put in the work if you want to grow yourself and your account. Avoid this shortcuts as they only end in regrets. If you visit the meta board, you'll see users regretting for the plagiarism they did. You can learn from their mistakes and better yourself or you pay the price when you engage in this crimes in the OP.
