TL;DR - If you're an "Elite" member on HDF and didn't use it for quite a time, login now before you definitely loose your account.
HDF has made a lot of changes and bug corrections this past year, including finding and correcting a bug in the inactivity rules enforcement system.
Previously, all "Elite" class members where immune to inactivity, which was an error. Now the rule enforcement has been corrected and 400 accounts has been deactivated.
There are few days remaining before a complete disabled accounts purge in early 2025. So if you think you may have been deactivated and don't want to definitely loose your account, better login again fast (and start using the site again).
