Been there, seen it. Also called the "downvote brigade". When someone posts something against the hive mind, that message gets voted down, but then also every other message by the poster in the thread is meticulously voted down to oblivion!
Also other kinds of malicious downvoting are quite common in Reddit.
Those things being said, I still do find the system of unlimited votes to often be quite fun.
Troll is a person posting an inflammatory message with the deliberate intent of exciting readers into a controversial response. This is the exact definition.
But the word is misused a lot, indeed. For example, just writing hateful comments, or messages with disinformation, is not trolling.
The scary thing about Linux is that they can do sometimes platform updates which suddenly break fundamental things like keyboard or ACPI fan control.
But then again, the bleeding-edge development process also allows to get all the new cool features quickly into the kernel.
When will people learn that trying to take down negative reviews just gets you more negative reviews and the spotlight.
You have to remember that there might be many cases like this where the negative review gets successfully removed and gets no public attention. That might be the reason why "they won't learn" -- because the trick might actually work.
