Yes, there are some almost reaching the 500SP, but I would reinforce the call for you to take another look because there are much more people under that value. She posts an image with a long list of users and you can clearly see some of them don't even have reach 100SP or 200SP.

I will leave you the direct link here for her post so you can see all the users names so you can select the ones you would like to help.

Everyone there tries to be most active they can, based on their possibilities and time schedule in order to be able to post and contribute. So it's just a matter of really check their work with some time and you will find a lot of people that deserve your attention to reach minnow level.

I have seen the posts, but it takes time to investigate each user. Some of the people there are not posting and others are doing low quality posts. That is why I prefer personal recommendations.
