I used to answer there maybe weekly or at least monthly, and I don't remember any spam activity at all. All posts I remember back there were asking for how to.

So no idea why the Reddit AI got triggered to ban the sub, but back then I noticed Subreddits were indeed banned quite often for whatever reason, with the Spam accusation as the default.

Now, one common issue was performance issue, like the player's response time and lagging. One simple solution to try is:

1. View, or Right click
2. Renderer Settings
3. Reset
4. Reset to default/optimal renderer settings

• Shaders also increase CPU usage especially Pre-Resize.
• Repeated editing of Matroska files, like repeated tagging (adding covers, deleting, saving, etc.), may result to slower playback performance of the file. Solution is to simply remux it with MKVToolNix, not FFmpeg.

With slower machines like Pentium 4, the lag or slow response time, and then the player's quicker performance after resetting are noticeable.
