Spammers have almost entirely left the platform. Some turned into prosessional downvoters while others are simply dead accounts. Others seem to have lost interest in blogging anymore since the price of Steem kept on diving, that's what I think is the main reason for many who left or just abandoned their accounts for a while. A small portion of us though might have found a meaning to the real life and didn't felt like posting anymore and spending hours a day in here. I don't like crowded places so it's fine for me the way it is.
