I just stumbled onto this thread. I never received any notice of this change so I checked my account. I had 4,467 points, all wiped out on Nov 28. Certainly not all were over 5 years old so I assume I got caught under the 12 month "no activity" rule. The problem is I did have several rentals over the last year, but they were all in countries where you don't earn points (e.g. Hungary, Malta). My most recent points activity was a points rental in Ireland in November 2023, so the November 2024 wipeout seems to follow.

Do I have any recourse here, based on the lack of notice or the overly strict definition of "activity"?
