The poster himself said that it was deleted because it was a double-post.
Double-posting is generally not allowed except under special circumstances (games and rounds is not one of them).
It should not be a problem because as I can see, your rules already accommodate for this ("if you post multiple entries only the last one will count").
12. No duplicate posting in multiple boards (except for re-posting topics in the local language boards if they're translated and re-posting marketplace topics in the altcoin boards if altcoins are accepted).
We don't know how this rule applies to games and rounds where the entry of participants' bet ID is different in each post.
can we get a heads up from the moderator who's responsible for moderating that section of the forum if they deleted the participant's post.
- can we prevent this from happening again?
