We have done that as well and I have to admit that a good amount of people are understanding and promise to change their ways - it's the minority that aren't who like to go crazy and take up 10-50x more time than what is needed and go on the offensive, threaten to leave and all that nice stuff.
Look at nosdos for instance, received a 1% downvote from @ocdb on his dog charity posts because there was a profitable bid bot vote on it and instead of just not purchasing bids or telling his readers to donate directly instead he went full dumbass with accusations, defending and now just editing out all his posts, leaving the platform while spam downvoting all of my comments. There are plenty of others who are now following me around in discords and even reddit and other platforms bringing this shit up in posts where I'm trying to tell people about Steem. It does not help.
Oh crap! I was hoping that kind of thing wouldnt happen.. i didnt see much of it... yeah i can understand that is a royal pain in the backside.. i guess it was inevitable... ive had a few of these types hounding me over the years, luckily they all left eventually!
Yep, ignoring them works most of the time. It's just something that needs to be done, luckily I don't care much about my post rewards as they obviously seem to. :)
