Of course not. I don't want to promote it in any way. If you couldn't find it yourself I am glad it's not that easy to find.
Lack of good tutorial is one thing, hints are another thing and cheaters are completely different thing.
About the tutorial you're right. That is one of the reasons this thread even started. We asked SE to put a good tutorial in the game because the current one is just a wall of text. You can learn from it (as I did), but it takes more time than learning from a good tutorial. And the current tutorial is just not fun.
About unranked players playing with hints. I see no problem with it. Learning from hints may be good. But playing with them in ranked matches is totally no good. If a machine plays for you in a ranked match, how can you call it a ranked match? It's plain stupid to give players something like "ranks" and the option to let the computer play for them. It's like they would add an auto-play on pvp. It just makes no sense to do that.
And finally about cheaters. Today I found a second cheater. I even made them admit that they've cheated. They controlled 3 different characters in a single match and had them on auto-play.
If you want to spot a cheater I recommend queueing on all types of matches in the middle of the night. Usually, they queue to full ranked match in hours when there are almost no players online. (Though in most cases they just gonna "decline" the moment they realise that not all of their characters are in the game.)
Two different cheaters I've met used the same tactic. Logged on 4 characters. Queued on all of them. Their main character had the addon set on playing as hints show and other characters tried to lose. (In one case the low lv characters left the game to speed it up.)
The losing characters were low lv alts that barely could enter Gold Saucer (they had exactly lv18, I checked on lodestone).
