Yeah for real. Especially for a F1 subreddit. Monday and Tuesday is the quietest period and it's not even coming off a race weekend. If they want to make an impact this should at least stretch into the weekend of the 17th.
Some subreddits, specifically r/cars says till the 14th and maybe beyond. It shows that they're willing to continue the blackout after the 14th if r/reddit doesn't change course.
