Posting to your own profile duplicate content is bad by anyone’s definition. Doesn’t matter who’s it is, after the first cross-post of a piece it ceases to be syndicated and becomes duplication on that channel.

If “it’s not against the specific written platform rules” is your best defence you’ve already lost.
