The contest doesn't guarantee that every entry will be supported and possibly get a booming upvote.

"guidelines for boming should not be support those posts who get SC01 and 02 only" ^@artist1111

Sorry that was in the previous case where we could submit posts that had been curated by Sc03 to 09. Like I said

New guidelines we have this section (I repeat)

Posts that received upvotes from @steemcurator accounts (@ steemcurator01 ~ @steemcurator09) will not be eligible, and thus should not be selected.

I understand your concern, As mentioned in the contest

Three authors will be selected and will receive booming support based on the rules and originality of the post respectively.

Random based on the administrative judgment following the appropriate guidelines. As I said, we are already looking at ways to give more value to the contest entries in terms of rewards.
