Since the last hardfork, issue 177, the payout system has been modified.
- Initial payout stake weight time is being reduced to 12 hours.
- After the first payout, a second payout time is hard set 30 days after.
Even with a 24h payout time, it has become close to impossible to sort out the duplicate posts, fake posts, fraudulent accounts, double posts, or any kind of posts that should not take the platform's money.
Steemit has some great bots running to detect and fight against these posts, for example 
However, we need to make sure this platform has quality, and genuine content only, to the extent of not becoming a platform where people quickly sign up, post some duplicated, stolen, or spammy content, and run away with the money after a mere 12h time period.
My suggestion goes out to limiting new accounts transfer possibilities to a certain degree of verification (human, bot, downvotes, community feedback, ...).
Verified accounts (timebased, SP based, postcound based, anything you like) could be limited to a shorter amount of time, let's say 24-48h range.
A system could be implemented that if a post gets X amount of downvotes, the funds remain locked until investigation?
Right now, underground websites are promoting Steemit as the quickest grab and run in crypto history.
What's your opinion fellow Steemians?
