When looking at the public world request forms, it seems pretty self-evident that not all reviewers are actually doing their jobs. Worlds are rarely checked as thoroughly as they should be. Only on certain days do the "good" reviewers come out, and only
then
do they properly review stuff like avatar materials and dynamic bone transforms.
This makes world reviews highly inconsistent, and makes the review's scrutiny entirely dependent on who happens to review it. And worse yet, some reviewers seem to not do their jobs properly. With the right timing, a user could submit a highly unoptimized or broken world, and have it almost guaranteed to be made public due to the reviewer.
Before the "avatar world" checkbox was implemented, worlds would often not be categorized as avatar worlds at all, further indicating the laziness of some reviewers.
Scrutiny and limits on public worlds can be a good thing. But they are utterly useless if only 20% of the review team cares about them. Please fix the underlying issue before you take another look at the limits.
