After reading some of your content, I advise to post it on D.Tube. The bots are still an issue but there is a dedicated curation team which will upvote good content in a video format. I do feel your content is solid so I'll leave that to you.
To add, I feel that the way Steem uses investment of votes as a method of valuing content, is not a great one as I could post a picture of a glass of Coca Cola and with enough investment, get onto Trending as you've mentioned. This is clearly not an indicator of good content but rather an indicator of investment backing. I don't know the answer to this issue but it's clearly not a good idea for Steem to be promoting content via by investment but rather the actual quality content.
Give D.Tube a try with an introduction with yourself, a well made video which you would be happy to give to absolute strangers on the street and hopefully the curation team notices you. The curation team checks for bots.
