So, what I see is a request for a boost on a zapfic post. Some curators are looking for longer posts to boost
And your 500 Point boost request was probably refunded because large boost requests are often refunded in favor of giving out many smaller boosts and spreading the Ecency voting power around to more people. But, like I said. Boosts on content will be discontinued soon. You will be able to spend your Points on new things!
That sounds great
