This is thanks to the Thanos Did Nothing Wrong subreddit, which as their name implies fully supports Thanos. As a result, the subreddit is revealing a new Infinity Stone in Thanos' Infinity Gauntlet every day, and once he has them all half the users of the subreddit will be banned instantly.
This isn't a surprise to the fans of the subreddit either, as it's been cleared with the Reddit admins. Here's the post from The Jedi Apprentice going into some detail about it.
"As you all know, I was in talks with one of the admins of Reddit. He told me that doing a massive ban the day before July 4 was a terrible
However, I presented a solution to these two problems, and I now have their permission to ban half of the sub!
The random 50% ban will take place on July 9. The admins are designing a bot for me that will allow me to do the job in a quick and easy manner. So, be patient, and thank you all for your support."
According to the subreddit, this should also qualify for a Guinness World Record for Most Active Users Banned from an Online Forum in One Hour. The best part is that the whole subreddit is pretty excited for the event, with no one knowing who will be sparred. Users will also unsubscribe if they are banned so the thread reflects the real numbers, and there's a petition for a bot to send a "You have been spared by Thanos" message to those who make the cut.

So far Thanos has the Power Stone and Space Stone, so it seems destiny is coming very soon.
