How often do ISP filtering rules change?
ISP filtering is constantly evolving:
Machine learning: Models retrain continuously based on new data. Changes happen daily without announcement.
Policy updates: Major policy changes (like Gmail/Yahoo 2024 requirements) are announced in advance.
Algorithm tweaks: Subtle adjustments happen regularly without disclosure.
Reaction to abuse: New spam patterns trigger filtering updates.
What works today may not work next month. Continuous monitoring catches changes before they become crises.
Harbor rules evolve constantly. Stay current or be surprised.
