I have noticed this too. On one hand I can see it is difficult being a newbie on Steemit. On the other hand it is spam if that is all they are doing and not contributing intelligently and cultivating themselves and their audience. I think this is so important. And as you say it brings richness to the community and builds reputation. I am really enjoying steemit. I finally have found an outletfor my writing and I can post to my hearts delight. If I can share this delight with others then that is a true gift. 😉
