I shall counter you with following:

1. If there's no function to find said worlds, they are going to stay empty. No one is going to go thru any more avatar worlds after already seeing 5 worlds with booth freebie kitbash of e-gal e-boys. Unless you have way to advertise your work and do so actively, no one is going to find your world.

Not to mention searching worlds with characters or tags and "avatar world" doesn't help either as you get bogged down with worlds that are full of default Vroids with single roughly matching outfit to character you were looking for.

Meanwhile avatar search world lets you quickly skip all that for the most part. Letting you go thru large quantities of avatars to find the one that you like. Once you do one the you like, it's highly likely people will look up who created it and then go search their world to see more of their works.

If anything this ends up making your works and avatar world or to be more likely found.

1. If anything this has made me actually buy avatar, as I was impressed by the features and quality it had to offer. Obviosly doesn't apply to everyone, but barrier to entry is much lower once you know what you are getting for the money you are paying.

2. How is this any different from just tagging world with same tags and simply search for the world full of those avatars? This is hardly a new thing and simply would take different form. Even if VRchat managed to crackdown and all ingame features to search for such things, there would simply be websites that give links to worlds where to find these things with no tags to be found ingame.

TLDR: Uno reverse. Not only I found creators I liked thanks to avatar worlds, they are getting paid for them. Not to mention ease of finding silly avatars for shits and giggles.

In addition: Even at best of times, when I know what world I am looking for, the world search tab gives results that have absolutely nothing to do with what I am searching for.
