I think there's always going to be people who seek personal gain without thought of those they harm; History is full of it...Look at DeBeers and their blood diamond trade for instance...Anyway, here, in the digital world, it's not as easy to fly under the radar and bad behaviour can be clearly seen for what it is.
I believe it is up to the community to redress that behaviour, as it is doing, when it's revealed. By redress I mean brutally stamp it out.
Having said that I believe there is a way back for those who have acted poorly in the past. Redemption for wrongdoing is available and should be permitted by those of us (the community) who have been affected by those wrongdoings...The community at large.
I've used the word community here a few times and in reality it is a community we are involved in...No different to a community of cave-people. Imagine a cave-dude acting poorly within the caveman-community...(Eating all the sabre-tooth tiger whilst the other cave-dudes were sleeping)...They'd get clubbed to death or reprimanded in some way at least, maybe even eaten themselves...Here in Australia Aboriginal tribal law is still practiced in remote communities (spear to the leg etc.) I'm serious.
Steem isn't that brutal, we're a sophisticated, classy group of intelligent beings and have such traits as understanding and forgiveness...Right? (Maybe.)
As someone who has benefited from 100% downvotes over a period of a few months, on every post I made it would be easy to simple want to spear someone through the heart...However I'd rather see those that engage in poor and anti-community behaviour simply make an apology and get on with whatever the hell they wish to post, even if its nonsensical poetry, and get with the program for the benefit of the community and themselves. I'd be happy to welcome them back from redemption island and back into the fold...Provided the bullshit stops. I'm happy to give people one chance. One.
You may note I used the words benefited from 100% downvotes...I say that because during that period of getting DV'd so much the community rallied around me, supported me and helped keep my attitude on the up...That's community mofo's! That's what it's all about. It will not be forgotten.
P.s. I kind of agree with @bashadow also though...Sometimes change isn't possible...I don't know why...Maybe Sigmund Freud could tell us.
