You are right, its very unfair and it makes it very hard for new users to get very deeply engaged with the steemit platform... what bothers me is that I only can use steemit a lot at night and not much in the morning cause the bandwidth lowers severely...
And you mentioned a few things I did not know. But thats why I usually limit my steemit activity to 3-4 New Members welcome daily, 4-5 Feed Commenting/Upvoting, post 1 of my own blog articles a day and reply to 3-5 comments. Thats it daily for me. :)
