Neat shots! I agree with your thoughts on the social media algorithms! It's a shame it's that way and hopefully some day they improve how it works, it used to be much better and it just gets more and more restrictive and more and more pay to play so to speak.
Also that's cool you've had such positive results on Unsplash! I should really take some time to post some of my images there. Also I appreciate what you said about sharing and not expecting anything back! Great mindset. :)
