I found a user on Reddit who admitted to being a grade 8 student, and playing on stake.com. I tracked his username from his previous posts and comments and messages support about it. But they refused to do anything about it, which means they're knowingly allowing underage kids to play on there website

Hey there.
Thank you for reaching out.
We're sadly not able to act on the information that other users provide us regarding players as there could be a harmful factor involved.
Note:I have photographic proof in the form of screenshots.
