It's the result that counts, though, not the "thought and effort". There's no way to measure thought and effort. You fandom nemesis might write you a low-effort gift without bothering to tailor it to your requests, and if you happen to share a similar id, you'll still love it. Someone can put a lot of effort into badfic and it's still a bad gift. People aren't mindreaders, so they have to judge the fic by its own merit, but by whatever effort the writer may or may not have put into it.
