I have an Ender 5 Plus with some upgrades ("Old" MicroSwiss Direct Drive, Exoslide XY, custom shroud) and I occasionally have the issue in which the Cables for the Print head as well as the Filament Feeding Tube interfere or get caught on something on the printer.
The most recent example was when I printed (or wanted to print) something and in the middle of the night I woke up and checked up on it and it had a layer shift. Turns out that the filament feeding tube got caught in the X belt of the exoslide and prevented it from moving properly.
I already printed some brackets for the cables on the backside to the print head but the tube is still fairly unstable and flopping over after some time. The same with the filament feeding tube, since they are delivered in a spiral they are fairly fixed in that position and while I could and now have oriented it into a position that it wouldn't get caught, I need a more permanent solution.
What I am looking for is something to keep the cables upright, maybe even some "boom arm" that has some clips on it that pull/hold the cables up but also not as tight so that it interferes with anything...
Here is an image of my Printer. which pretty much shows the issue.
Short answer: Because their motivation is to win!
I read something about this in the Book "Introduction to Game Design, Prototyping, and Development: From Concept to Playable Game With Unity and C#" by Jeremy Gibson a while ago, maybe that can explain this a bit.
Basically, every Player has some Intention or the "Player Intent" which is described by the Personality Types of Richard Bartle. For example, you have:
And then you have two others that you will be encountering:
So, the motivation to "cheat" could either be that this player doesn't really care about the game, is able to get away with cheating and just wants to beat the game. According to Jeremy Gibson, a cheater might not cheat if they can win legitimately but I would argue that cheaters are usually not great players in the first place so the bar would be pretty low for them to "win legitimately".
As for the spoilsport, this is extremely hard to work against or prevent because the motivation isn't about the game anymore but other players, to make their experience miserable so that the spoilsport can gain satisfaction from it. Hence also the use of "don't feed the trolls".
With that being said, when you ask why someone would cheat, the question would rather be "What is their motivation" and the answer to that is "to win the game, at all costs". And, most of the time, they will get away with this because they apparently cannot be caught as quickly as they can still continue doing it, if there is any action against them at all.
