I am not aware of Reddit experimenting with blocking mobile browsers. However, it’s important to note that information and developments can change over time.

To get the most accurate and up-to-date information about Reddit’s policies or any potential changes related to blocking mobile browsers, I recommend checking official Reddit announcements, news articles, or Reddit community discussions that might provide insights into any recent developments. Additionally, you can visit Reddit’s official website or their support pages for any official statements regarding this matter.
