Hey welcome to Steemit! careful uploading many videos back to back in the same hour. its floods the network and people start to downvote your posts. this might be why your reputation has gone from 40 to 25 in one day. You do have good quality content though, it shouldn't be hard to bring that reputation up. Let me know if you ever have any questions about Steemit.
.
Not sure how many videos you have saved, but you could just upload like 3-10 everyday. I'll help promote your page. Do you have a page on youtube?
Found your youtube channel, over 500 videos! do you plan on uploading all of them?
