Do any other DU'ers note this happening?

I check DU many times every day. On almost all days, maybe every day, I see multiple posts of the same OP. Since I get up at the crack of dawn(yes, I have a kitty), I note that the same post appears many times during the AM. Not one of those 'oops' double clicks things, these are separate posts of the exact same things but the times are different by minutes or hours
Is this unusual or is my computer doing something funny.

Perhaps the poster has a way of duplicating their post. The reply and rec contents are different so I think they are repeats of the same post, seen at a later time by others.
Can someone explain?

I'm not sure this lasts all day as I am not on line as often after noon, back in the evenings.
If this is something unusual to me, I would be happy, starting tomorrow AM to post links to several of these same posts.
Just curious.
Thanks
