I'm sure there are HUDs out here that do the job like lawena ( https://lawena.github.io/ ) or something but if you want to do it yourself then you can try the following:
(you can also use hudlayout.res but that doesnt work for me for whatever reason)
Go to your HUD's file > resource > ui
there you should see things like "huddamageaccount.res" (which should be for damage numbers) and when you open It you should see a variable called "visible", if you want to disable something specific in your hud you have to set "visible" to 0 (read the name of the file before you disable it as there are things you don't want to disable like the menu GUI) https://imgur.com/a/yvxVRxN

I'm not %100 sure which files you have to open and scroll through and set to 0 but as a starter "spectatortournament.res" should be something you check out
Scroll through the folder and check the names of the files, open the ones that are related to what you want to disable, press CTRL+F and type "visible" then quickly set everything to 0
(make sure you back up your files)

You can type this command into your console if you are having trouble disabling the spectator side hud: "hidepanel specgui" and "showpanel specgui" to undo it

I really really like jamiroquai, and maybe bernard herrmann just because of the taxi driver soundtrack, ATCQ's q-tip is really good too

I'm stupid but I feel like banning sniper would mean teams who rely too much on sniper would have to rely more on holding doors (on last holds), would have to do proper sacs or as you said use spy and people wouldn't have to wait 2 minutes for the sniper to take a proper shot (which sometimes never happens in livecasts)

As for " If you ban sniper, every time you would pick sniper, a spy is picked instead and does the same job, the flow would not be altered so much", you are correct but I believe spy is way more fun to watch than sniper as you have to sneak in and do some sort of distraction play beforehand, take your time with it and make sure you aren't noticed + even If there Is a spy people can still hold doors (and don't have to hug a wall and sacrifice vision). Once you make a mistake with spy you are 97% dead (sniper gets way less punishment) also It's pretty funny to watch spy players mess up and go for trickstabs to salvage whatever they can lol, so i don't think its really fair to compare spy to sniper as atleast a good spy player is counterable, but decent snipers feel like you just have to sit and pray and can output WAY more damage, I don't think pyro affects the flow of 6s as much as sniper does even on last because you don't really see pyros saving the last point that muuuch but its quite common to see snipers land a hero shot and drop the enemy medic

+i dont think its fair that in a game where most classes get obliterated once they make a slight mistake, there is a class that can get in absurd positions and still get away with it

Okay but what's the end goal here? Sure you ""trolled"" the "annoying nerd" but you also trolled the 4 other people on the team

Yeah, I'm also worried about volk's chin as he got knocked-out back to back with little to no rest inbetween them, but I am 100% sure volk has learned a ton of stuff from his previous fights but lopes Is really dangerous too so I'm not really sure
