Hatespeech/Harassment is one report category. Whether it's actually hate speech or harassment is irrelevant.
As far as the forum Report Players guidelines go, it's considered Harassment, as per TP's quote;
Hate speech. Phrases against race, sexual orientation, gender, or religion fall under hate speech. Pedophilia falls under this category as well. This will generally result in a permanent ban depending on severity.
As you can see, it isn't hate speech by those standards, as those standards are group-based, this is individual-based. (Not that it should matter, but.)
As for your example, you're pulling a thread from the beginning of last month, vs 2 threads from a few days ago. Not exactly the best comparison.
I wouldn't look down at inciting suicide as either one or the other, and personally, I'd handle it on the forums if reported, but that technically goes against the guidelines for Report Players when you're reporting it.
As far as Trial System and reporting it in-game goes, it's all one-in-the-same, so it really doesn't matter.
Apologies for any confusion. I've asked that Judges just close reports that are posted in Report Players that follow the rest of the guidelines correctly that incite suicide anyways if they come across them.
