First realise that just like FBT Heaven or old Void, jhp always has one isntance where "cool kids" go and that instance will probably be full and unavailable to you as a rando. Japs have lots of small circles, there's japs that know each other from matching world and they don't really care for gaijins. They will almost always be in bath or hiding on 5th floor.
There's twitter gooks, they all come in at once, if you're not twitter friends or discord tranny they basically don't pay attention to you.
There's dance niggers and DJs who know each other from some obscure dance parties, they will only care about their event friends.
There's spics who hate everyone who isn't spic and they crash everyone who offends them.
There's eurobooths who always sit in bathrooms and avoid NAs.
There's residents who literally live in jhp and know everyone and coomed with everyone so they gossip like teenage girls.
And those groups have lots of overlap so if you go and block few niggas from one group there's good chance you might end up hated by few other groups too.
Good way to tell if you hit sikrit klub instance like that is if it's basically full and people aren't in pairs but rather small groups and if more people keep coming in after softcap of 30 people is hit. If yes you're basically out of luck unless you're part of some of the groups there or friend of someone in there, If not you can just hope that someone will be interested in your avatar or go to one of the overflow instances where TDAs and desktoppers go
