As sad as it is, spam seems to be here to stay (for now anyway). I just choose to ignore it as much as I can and focus on what I can do better - and I have also managed to educate a few new Steemians on what they are doing and that it could be percieved as spam - some people dont even know what they are doing is coming across as spammy.
Scams on the other hand, I hate them with a passion and flag anyone who looks even remotly like they are trying to scam -anyone offering upvote services with a link now I pretty much flag.
As you say 'spammers gonna spam' so I mayswell just move along and get on with life
