I'd love to be able to recommand worlds or post warnings or hints, and be able to check these kind of comments from other people. The tag system is nice but without a proper introduction video or description it is hard to find gems.

I've been sayin' this for a while. The one big downside is that I have this add-on someone made for SDK2 worlds, and while it is very helpful and I love it, the big problem is the amount of spam and slurs I get in my world as well. But you have to take the bad with the good...it should be something like Jumping in worlds. Optional, but easy to add.

Many times I’ve found it very difficult to exit the game and try to find an external method of contacting a world creator to inform them of glitches or broken features or just feedback in general. This feature should be essential with the world creator having rights to delete any TOS violating comments that the system may not pick up on.

This will be even more important with Udon worlds since as creators we need to be able to tell when a world has issues and what issues it has so that we can improve it. The current report system falls short of this completely. My Camera Test world has an avatars-nudity tag despite not having any avatar pedestals in it and I have no way to judge if those reports are due to some issue with avatar transparency, the world, or something else like people trolling.

People are already making prefabs for people to put in their worlds that allow feedback to be posted from inside the world. Take control of the situation before people start using these in all of their worlds and causing feedback and to be passed through another server out of VRChat's control.

Moderation of these comments is a silly reason to prevent feedback on worlds altogether. Allow people to report comments that are intended to harass, and allow the world owner to either block feedback for the world or make all feedback private.

Allow " LIKES " to the world instead ... since Facebook is partially remove it anyways...

​The shit posting, memeing and spamming would be out of control. 😅

Not to mention such comments being a moderation burden.

And putting the right to delete the comments in the hands of the world owner would just lead to them censoring negative feedback.

Comments to be made on the Website rather than in game. With those comments ...say recent post would be previewed on loading screen

I would like this idea. Probably difficult to do in game since vr keyboards to type on is rather tedious so they should also implement it on the website in case someone wants to go back and review the world or comes across it on the site and has been there and would like to leave feedback in general.

How this wasn't a core feature of Community Labs is honestly mind boggling. They added a system where worlds are effectively quarantined when they are first uploaded and submitted to be made public, but have no way of reporting issues found in the worlds to the authors (or just giving general impressions).

Authors shouldn't have to accept random friend requests (be it in-game or on other platforms like Discord) just so people can report bugs to them.

And as you say it could be used to make general comments which can be good for authors and people interested in the world. As long as there is a way to properly moderate what comments are displayed (potential for things like harassment or spoilers).
