Should we Support Steem Sports

Hell Yes!

posts spam those not interested in sports

You can say this for any popular topic.

posts use unreasonable portion of reward fund

The Community votes on the post, how is voting on what is popular suddenly unreasonable ... simply because the vote did not give the result some expected?

Oh wait, I'm in America. Never mind. ;)

Also keep in mind that you once said the payouts that people catfishing the Community received weren't a problem because they were putting effort into the post. ;)

I would propose that the blockchain add native support for the Steem Sports use case and make the entire process as trustless as possible. This would involve adding a new custom post type with custom rules for dividing results.

+5%

Demand to increase individual bets would drive SBD purchases and STEEM token value.

Agree 100%. This could be yuuuge for STEEM!
