Duplicates happen.

On a forum like this with the rapid posting rate, I don't see that more than one posts on a subject is that bad - often I will miss seeing the first time around and catch the second or third.

It happens.

It's only a message board. No need to feel like you need to self delete.

On DU2 they used to give you a list of most recent threads to avoid dupes. Don't delete yourself, I like your posts!
