Recently, X's risk control has become extremely strict. Since the beginning of the month, I've lost five hundred followers.

It's not unfollowing; they've all been banned... The specific reason is unknown. Can someone explain? The proportion is really quite high, about 3%?
Old accounts with the three-piece set and well-linked high-quality accounts also have many being banned.
All kinds of spammy private messages asking for dates every day, why aren't they banned?
They only ban users who silently view messages while spamming push notifications.
