Someone please explain this for me....

My Brainly account was "banned" or "blocked" for 4 days. I couldn't comment, ask any questions, or see my notifications for those 4 days. Before it was blocked, I had 3,000 points, 11 Brainliest, Expert Rank, 354 people helped, 207+ Thanks on my account, 60+ achievements, and 137 questions answered. After being unblocked, I had 92 points, 0 Brainliest, 0 questions answered, 26 people helped, only 5 achievements, but I am still Expert Rank... What does this mean and why is this happening?
