But I've also seen some of the people I follow reblog a lot of posts. This ended up taking up too much of my feed. I ended up unfollowing them.
Same. I take reblog as a little evil, when my feed becomes diluted with 5-10 posts in a row from authors I dont follow, I simply feel sick (as I am a natural folk with informational disease and limited info bandwidth; I also used to manual curating...). I do very little reblogs myself, and frankly, adore the same policy from the ones I follow). 🙃 When information becomes diluted at high percentage - it turn into a noise - and one have to switch off the fridgebuzzing.
