I don't think this tip should be kept.
First of all, reread the title real quick. This is my opinion.
Tip: "If a player makes you uncomfortable in game, report them."
Now, I'm a firm believer that you should report someone for doing something report worthy, it makes the world a better place from the perspective of the players who don't appreciate damaging behavior. But on that note, I don't think being uncomfortable is a reason to report a person. There are A LOT of things that can make a person uncomfortable, even more so depending on the specific person and their background or views.
If I start talking about Trump, would it make you a little uncomfortable? If I started making self depreciating jokes or kms jokes, would it make you a little uncomfortable? Does ( ͡° ͜ʖ ͡°) make you uncomfortable?
Well, you get the idea at least. None of these things are reportable or against the rules, but would still fall under "makes me uncomfortable". Frankly, I don't think this tip should be kept, or it at least should be rephrased.
