They increased the req to get into it again.
https://youtube-creators.googleblog.com/2018/01/additional-changes-to-youtube-partner.htmlStarting today we’re changing the eligibility requirement for monetization to 4,000 hours of watchtime within the past 12 months and 1,000 subscribers. We’ve arrived at these new thresholds after thorough analysis and conversations with creators like you. They will allow us to significantly improve our ability to identify creators who contribute positively to the community and help drive more ad revenue to them (and away from bad actors). These higher standards will also help us prevent potentially inappropriate videos from monetizing which can hurt revenue for everyone.
Assuming an average watch time of 2:30 per video (typical for many channels) then 10,000 views would be just over 400 hours.
Which means 4000 hours is TEN TIMES HARDER, at least in some sense.
