And my question to the github management is why can't any registered user report any low effort useless or offensive comment to the moderators, whoever they may be, like almost every other online discussion group outside of 4chan?

It's a call of duty meme, at some point your character is at a funeral and F is the action button and there is a prompt on the casket "press F to pay respects"

I disagree that it's a joke, because they're absolutely nothing funny or clever or original about it, but you're right that the point is to jump on a bandwagon, and it's intentionally ironically disrespectful of everyone's time and attention, which is also the point. It's really just a spammy childish 4chan troll.

All Due Respect: Press F for Farce. Recently, Call of Duty: Advanced Warfare became roundly mocked when images showed a funeral event where the player is asked to “Press [F] to Pay Respects.”

>On the other hand, Call of Duty forces the player to Pay Respects for the game to proceed. It’s a mission objective just like any other, complete with an interactive reticle floating above the coffin. Furthermore, it’s embarrassing to ask the player to take this action explicitly. This is a military funeral! What else would you do, blow a raspberry? It’s no wonder players feel insulted.

Ludonarrative Dissonance:

https://en.wikipedia.org/wiki/Ludonarrative_dissonance

>Ludonarrative dissonance is the conflict between a video game's narrative told through the story and the narrative told through the gameplay. Ludonarrative, a compound of ludology and narrative, refers to the intersection in a video game of ludic elements (gameplay) and narrative elements. The term was coined by game designer Clint Hocking in 2007 in a blog post.
