Not sure how easy this is to fix but if you go back to like 3 years ago when curseforge could be browsed at curse.com and minecraft.curseforge.com those redirects dont happen anymore. The first one redirects to fandom who bought the entire company Curse except CurseForge from twitch (why curse.com) redirects but some old websites still link that legacy link. the latter just straight out 404s which a similar fix can be used
