Do stack exchange sites prohibit cross posting outside stack exchange?
Is it allowed to not indicate identical posting on stack exchange? ( One benefit is to receive independent responses, and the other is for account privacy.) Some sites encourage sharing posts of stack exchange sites with them, although I am not concerned about "sharing", but identical independent posts, and the order of posting might matter (where posting happens first: SE or other sites).
Is it appropriate that a user on stack exchange accuses another user of doing so?
It is not specific to U&L. I don't ask on meta.stackexchange.com, because they have been too "friendly" to me.
