I don't want to go into details to give people ideas, but don't you think it would be very easy?
What happens is that it would cost you more work, if for example you have a Facebook account with a certain number of friends that serves you for the bounties, then you would have to start from 0 and create another new account and get friends.
It's not that easy to get those so-called legit friends, the ones asking for friendships over twitter or FB or any other social media network are themselves not looking like a legit account at all, all your relatives and your friends will block you pretty soon if they see you sporting 20 links to ICOs or Defi all day long.
What some of the smarter spammers do is grow multiple of those accounts so when something gets banned they can replace the whole identity but this comes with a problem, that's greed! When you have everything that is needed for an alt, why not start using it so you can double your income, and this is when you get tagged for having an alt, and all your backup fb/tw/yt accounts are linked and you have no other thing to do than trying to keep using these till you grow some others.
I don’t want to insult or generalize anyone, but most of those caught breaking the rules mostly come from the same countries where living by the rules and moral values are at pretty low levels. In other words, the way they behave in real life, they behave on the forum, with the difference that they think that the forum can be anonymous to the extent that no one will understand that they use alt accounts.
I don't think it's just about some countries and more like the how big of a chunk a certain social class is in some countries, on top of that the average money one could get with an easy job and the lack of other opportunities. It's an accumulation of factors, with the cherry on the cake being the fact that some countries are ravaged by a lot of crime, theft, etc etc things like plagiarism or having two accounts on some forum look like, are you serious?
Sometimes I try and I think could understand somebody having a shock to hear copy-paste is getting him banned when going to his "workplace" he witnessed one shooting and two carjacks.
Not an excuse but probably moral values are influenced a lot by the value of your wallet.
