// of j of the last k entries this session, the action will be blocklisted for a
// set duration. Persistent: if the user has opted out of j of the last k
// entries, the action will be blocklisted for a set duration. Host: if the user
// has opted out of threshold of the last history entries for a specific host,
// the action will be blocklisted for a set duration. Type: if the user has
// opted out of j of the last k entries for a specific type, the action will be
// blocklisted for a set duration. This is the in-memory version of the block
// list policy. This object is moved from the embedder thread to a background
// thread, It is not safe to access concurrently on two threads.
