People losing whitelists?

Lately I've received several complaints about people logging in the find that their EE Whitelists have been removed without their knowledge/permission and I was wondering if someone could look into this. Maybe there's some crazy guy running around removing all EE's whitelist or maybe its some kind of sever error but I hope we can figure this out soon.
 
tbh probaly something with donating for gvip, it probaly auto whitelists but isnt suspose to so insted it removes it after a certain amount of time.
