It is "appeal to authority"

Here let me call an athority to make my point seem more atourative.

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

wiki agrees with me . my point is more important because i am an authority by link an authority!

It is well known as a fallacy,

basically if someone has to tell you who they are and why they are to be believed you should never listen to them!

op is trying to use reverse psycology to get poeple ot buy more loot boxes! by striking up anger ans anger releases adreanlina and causespeopel to change behavior.

because more people do not buy loot boxes than do buy loot boxes ops post is going to actually get more people to use loot boxes!

similar to how when news companies tell people to not kill themselves, more people get the idea to kill themselves and you get more suicides by telling people not to suicide.
