He's completely entitled to flag any post he feels is abusing the rewards. And his particular reason is: if you use a bid-bot within the last 3.5 days. That's why you might get flagged. He's letting everyone know why he's doing it and giving them all a heads up, so if they do decide to promote after the 3.5 day threshold they are risking a chance to get a flag. Sure, if your post is of low-quality then it deserves to get downvoted, as you say, or simply neglected by the community, but it's also in his right to be able to flag posts. Also, before the cat implemented the 3.5 days time-limit, abusers would buy votes for their post at around 6.5 days which would reduce the time @steemcleaners would be able to remove rewards.
Sure, you may not have a high vote value and hell, neither do I, but why can't you just stick to using the bots within the first half of your post's life? Why isn't 3.5 days enough time to pump all your SBD into it? I use bid-bots and only use them within the first day, maybe the second day at the latest, and I find it more than enough time to promote my posts. But then again, I'm not relying on Steemit to feed my family and this is just a hobby for me, writing a blog about my travels.
Maybe everyone else is just driven by the dollar sign at the bottom of their posts and they lose sight of what this platform should truly be about.
Maybe @Grumpycat and @themarkymark, with his amazing blacklist, could team up and hunt down more wrong-doers abusing the system.
