12 hours ago, a community member sent you a PM, and you never replied. Something about MQA because it was started from a post in this public topic.
2 days ago: an automated private message was sent to you saying that your message was automatically hidden by the system due to the fact that it was flagged as off-topic. There were no other people in that PM thread and you never replied.
Your previous PM was from 10days ago, and included something about a public post in the for-sale area of the community… something about Forza Audioworks. @AceRimmer replied to that.
The PM from 2 days ago was about the post screenshotted above. Given that the thread was about what MQA content we are listening to, your post was indeed off-topic.
Looking at that screenshot above, that sounds like the post you are talking about. I believe you have misremembered that your post was public and not a PM.
