I think this feature might be useful for people that don't want to go to specific types of worlds that aren't covered by the default content filters. Some people, like myself, have trouble with horror worlds because they're really intense for us, but not intense enough to elicit the extreme horror tag since other people can generally handle them just fine. Some people don't like specific types of worlds like clubs or maybe they found a world with too many flashing colors and want to avoid it in the future so they don't give themselves a seizure. Would also be good for people that are trying to stop addictive behavior like gambling and need to block worlds with casino type games and people who don't want to see AI. Blocking a world wouldn't necessarily even affect a world's metrics as it would be just less people going there.

There are certain worlds that I do not want to see.

It makes me very uncomfortable when these worlds appear on my screen just because my friends happen to be in them.

I would really appreciate it if you could implement a feature that allows users to block or hide specific worlds.

There are worlds that otherwise do not fit any of the existing Content Gating categories that I still would very much prefer to not see in my Friend Locations menu or in the World Search for a variety of reasons (made by a user I have blocked, bad memories of the world in general, etc.).

An option to manually add individual worlds to your content gating settings would be a good solution to this. It's already possible to do this with individual avatars via the "hide avatar globally" option so it'd only be fair for an option like it to exist for worlds.

World favoriting is planned, but I'd also like to bring up world blacklisting.

Some worlds just crash me, it'd be convenient if I could hide these worlds from my list/search and see whether or not the world my friend is in is one that I've blacklisted (because it crashes me).

And of course, some people may have other reasons for blacklisting a world. Reporting crashes is good, but I play desktop on a PC with an old graphics card that doesn't meet the minimum requirements, so I don't really expect the game to be optimized to work with what I have - I plan to get a new card eventually.

If possible, I think it would be a good idea to have the option to hide specific worlds we can choose so it doesn't have to pop up in friends playing / the world pages. Not only just a filter to filter out certain keywords/tags of worlds, but the ability to also block whatever specific world you don't want to see from showing up at all!

I personally don't have problems for worlds I'm seeing while scrolling down, but there are people who feel really uncomfortable seeing certain worlds even scrolling through them, such as inappropriate worlds that people feel uncomfortable with seeing, or worlds that can bring bad memories to those—and I think that this feature can help players feel a bit more comfortable on VRChat! :)

This might be more of a small feature but can be really helpful for those that need to hides/block certain worlds or/and tags so they don't have to see them c:

You can block users who you do not wish to see, it would be great if you were able to block worlds. This would simply prevent a world from being shown to you in the explore worlds menu (Variety box, New and trending etc). Of course it would still show up when manually searching for worlds using the search function. If friends are in a world, then in the social tab it could just show the friend as being in a private world. But that's less important. It's mostly about being in control of whether a specific world is served to you on the worlds tab.
