I flagged this question as needs moderator attention and in my reason I wrote, is not a research level, but moderator rejected the flag. I want to know in which way someone can consider it as a research level?
If the reason of rejection is because I didn't flag it as other to close it, my reason is because I'm really confused about the use of migration (that I don't like it myself) and flagging for close (e.g this and this and many similar topics are contradicting each other and is not clear for me to pick which one as a rule, and I don't want to discuss a long time to make it clear, I hope moderators get managed to do it themselves), e.g in this specific question seems OP doesn't know the basic search term, then we should consider it as research level question?
