So, here is the thing that bugs me personally because I also understand it as a biased justification. And me calling it that is really bad. Still reasonable when you hear their side on things.
These one-star carpet bombings usually happen because somebody wants you to quit. Why? Because they see you as a threat. What are you threatening? Their paycheck.
Let's take... Okay,
@tantrayaan was recently top dog, right? I'm going to use them because they did make themself a huge target for this. What I mean is that they recently created a whole thread to celebrate that achievement of reaching #1 in Trending. And they are relying on a good amount of faith from readers to visit and tip or subscribe to them. That's a hefty sum for work that already exists on this platform and each word isn't a consumable resource; it's a static product that only grows the more they write. If someone had similar titles to theirs that was getting in their way, maybe they'd go in and sweep them with those shiny, single stars. After everybody here witnessed how passionate Tantrayaan was about that accomplishment, it's very plausible some jealous asshole saw the public announcement here and would go in to do that to them.
Bots make it real easy because they are more effective than a throwaway account, and as you experienced, they can reproduce while they're coming in from all angles. Really nasty.
Back to what I'm pointing out. You can see how that envy may affect another like the smiling rain of sunshine like Tantrayaan; there may exist somebody who is vindictive enough to go beyond ethical means to ensure they keep their cash cow from losing its exposure on the front page.
It's bad to reason out the whys, but you can see the logic behind it. It's an existing practice of comparative advertising in a brand war.
