I only do the "Daily Set" and they still did the cooldowns and later even blocked me from using CoPilot on my phone.
According to Google Gemini... "The most common consequence of "abnormally searching" is the loss of your ability to earn and redeem Microsoft Rewards points. A full ban that affects all your other core Microsoft services (like Windows login, Outlook, and OneDrive) is rare for a Microsoft Rewards violation, unless the activity is considered severe enough to warrant a complete suspension of the entire Microsoft Account, which is a much higher-level action."
And CoPilot says... "If flagged, Microsoft Rewards may:
Pause your ability to earn points from searches temporarily
Enforce cooldown periods (e.g. 4 searches every 30 minutes)
Restrict redemption access for gift cards or sweepstakes
Label your activity as “suspicious”, which can affect your standing
Escalate to full account suspension in severe cases, impacting Outlook, OneDrive, or even Windows login access
These restrictions are often automated and can feel opaque or unfair, especially for users who follow the rules."
