Pages with challenges disappearing from Forum Games

hi there! month or so ago I was curious about 365 challenge that for some reason disappeared from Forum Games, but then forgot about it for some time. now, that I renewed the page on General Asia Forum I've found out that some of my previous challenges (like 2022 year and 2023 alphabet drama/movie ch) disappeared too. is it some bag or they're just got deleted/blocked/hidden and why? or somehow the moved to another forum? I couldn't find anything...
