Oh I've had the comment sniping thing happen to me. Not only do they take your sentiment and juuuuuust change it enough, but they upvote theirs so it gets seen ahead of yours.
More often than not, this is on a comment thread of someone with fairly hefty upvote value (who can casually dish out $1 here and there), and they obviously have waaaaay too much noise in terms of engagement to see if someone is being ripped off.
It's very subtle this sort of thing too. Much easier to be sly than to rip off an entire post.
yeah, had shared this with someone and got put in contact with the person who runs SteemCleaners and they said it's becoming more common.
hopefully, there may be a solution possible such as addressed herein...
Interesting, its so they move to the top, get noticed and get upvoted by the OP? ohh man that is so freaking tacky. Smh
