Thank you for making the most descriptive and correct comment so far. I am trying to explain this too. Someone is constantly complaining about my account and I don't think my posts are being reviewed. Upon complaint, my direct posts are deleted and my account is ban. As you said, I will report unnecessary messages from now on.
Try as much possible to make quality posts, and see if they ever get deleted massively once more.
According BPIP, your Posts made per post deleted is quite low (7). It means that for every 7 posts you made, at least one gets deleted by mods for being low quality, off-topic or spam. It's the high number of your deleted posts that probably led to the temporary ban. But you still have a chance to redeem and change the way you post after the ban.
