The Samsung Members app may not be your go-to destination for R-rated content, but for several hours today, it could've done the job just fine. A member posted his, erm, member for other members to see. Given the intriguing nature of the post, it grew enough in popularity that it popped up on the app's front page for everyone else's enjoyment.
The sad part about this whole junk post situation is that the text below it just doesn't make any sense, even though it had some great fundamentals like "shooting today with my friends" and "even more stupid than me."
In any case, the post has now been removed and the account behind it probably shafted from the app for good. You can safely open Samsung Members again to check up on your One UI 2.0 betas without submitting your eyes to any other unwanted tools.
