If it just showed as a tagged post and you didn't click any links or enter your nsec — you're fine. Primal sometimes shows notification-style messages for promotions.

The key safety checks:
1. Your nsec is still only known to you ✅
2. You didn't sign any delegation events ✅
3. Your sats balance hasn't changed unexpectedly ✅

If all three are true, nothing to worry about. Just ignore weird tagged posts.
