Maybe some of the followers of this thread already feed some scammer account to jump in when it's worth doing so. We are now 2/3rd through the game and it's likely the reward for scamming will be 10Ƀ later on. Maybe I'm one of them trying to save my stash from cheaper scammers

Most likely it's 5h of work to feed an account to 100 posts and some users already have their sock puppet troll accounts that they can just as well make famous and start over.
My conclusion is more that 99% of all humans are trustworthy but 1% are capable of making huge damage. These 1% might not really care about 4Ƀ. These 1% are the reason we need rules and all kind of regulation a society basically.
