I have been noticing this issue too. As a new user, and someone who really has been looking for a platform like this, the spam gets to me.
I will definitely do something along these lines if one of my posts takes a ride to the top.
You're doing a service here.
Try not to let it get you down...there's only so much a minnow can do and...well...you know what you came here for in the first place. Focus on that and keep your ear to the ground.
As a friend reminded me just yesterday there's more good people here than bad so...that's something to keep the faith by...right? Follow your heart friend. :)
Keep on Steem'n on!
