I don’t think resource credits does jack. It only affects very new users but most spammers it isn’t even an inconvenience.
Downvoting isn’t always effective but it at least protects the reward pool. There are many spammers who persist despite rewards.
Well, I am surprised to hear that, because spam is far less troublesome than it used to be, and my impression was that your efforts, almost singlehandedly, were the reason Hive wasn't unusable due to uncontrollable spam.
Hive has been so reduced in userbase, perhaps not many bother to spam us.
Thanks!
A lot of the spam stayed on steem. Removing rewards tends to discourage spam but you still get mentally ill people like blipborn who persist anyway.
