I don't understand why Change “I must go and look for my brothers.” from active voice to passive voice was migrated to ELL.
I know learners are more likely than native speakers to ask questions involving switching a statement from active to passive voice, and there would certainly be a strong case for migrating "trivial" questions in this general area (assuming ELU doesn't already have a suitable earlier question that would justify duplicate closevotes).
But it seems to me the specific example above isn't at all trivial - it's downright awkward, and imho it deserves the kind of detailed analysis ELU should be more geared up to provide. To my mind, a suitable response on ELL would simply be This sentence wouldn't normally use passive voice.
Just so it's clear what Up/Downvotes for this meta question should mean, I think the question should not have been migrated. So upvote if you agree, and downvote if you think migration was the right thing to do.
