I vote B. Machine learning algorithms can learn to identify spam posts based on a wider range of factors, such as the content of the post, the user's behavior, and the context in which the post appears.

https://cloud.google.com/blog/topics/developers-practitioners/how-spam-detection-taught-us-better-tech-support "Borrowing spam tech (...) Those engineers had thought through “how do we detect a new spam campaign quickly?” Spammers rapidly send bulk messages with slight variations in content (noise, misspellings, etc.) Most classification attempts would become a game of cat and mouse since it takes classifiers some time to learn about new patterns. Invoking a trend identification engine using unsupervised density clustering on unstructured text unlocked the ability for Gmail to detect ephemeral spam campaigns more quickly."
