Who is an older user is irrelevant on Heyuri, you could have came here last month and conform to Heyuri's culture better than someone who has been here for over a year, especially if they are jaded enough that they stopped having fun on the internet.

That aside,
While it's understandable that you may have no reason to view some content on Heyuri due it being incompatible with your fetishes (eg. there are even staff that hide rorikon board, or I don't look at 3D Girls board often), I've been historically against a filter/post hiding system - and we actively deleted posts of users who shared userscripts for hiding posts back when someone was sharing pictures of his fecal matter on the imageboard. It's because I believed a Heyuri user was ought to just be able to tolerate looking at content they didn't enjoy in a good-humored way.

Right now we have a filtering system you can make use of to hide any post you don't want to see, and once you do as much as simply hiding the single thread you created this thread for, there isn't any mention of gheyness on any other thread among recent threads, or rather for the sake of being precise, there isn't even a single other post about homosexuality or being gay, or even about cocks or boys/shota etc I see in the threads across first 3 index pages of the Off-Topic board (or possibly more, I didn't bother checking)

This is far from the first time we have a discussion over some content a portion of users don't like, but noone ever adds anything new to the topic.
