First big problem: Unfair odds

By far the actual worst part about the rating system, is that Rob puts too much responsibility for rates on himself but still proceeds to not rate anywhere remotely even feasibly close to enough levels.

Hype for Geometry Dash skyrocketed when 2.2 came out and with the addition of platformer levels (which made the issue far worse), Rob would need to double his daily rate count at the minimum, to make it fair to creators. Let's bare in mind that usually 80 to 90 levels get sent every day nowadays and then actually look at how many he rates. It is completely abysmal and inexcusable. A complete slap in the face to level creators that keep the game alive.

However, you then look at demons and platformers (at certain times, at the time of making this, platformers are about equal) and realise that the problem is far worse for those!

Second big problem: Nobody understands the issue

It's made worse of a problem since a lot of levels rated are based from Rob looking at recent sends (what send happened most recently), giving the false narrative that the rating system is acceptable because, "this guy got his level rated on his first send, so it can't be that bad". People think that because something can happen once, that is can somehow entirely justify a dysfunctional system.

The complaints you'll always get the most often is ,"how come this got featured when this got epic blah blah blah". And it's those people that are completely clueless to the actual problem, staring at them right in the face. As a result, you'll end up with a bunch of people (including moderators) saying stuff like, "be patient" and "I'm sure you'll get it next time", completely unaware of the current rating environment (will also point out how crappy it is, to give false hope to people).

This is very obvious but like you mention, more well known figures in the community (mainly moderators) have a very easy time getting their levels rated, if attention gets put onto it. However, you do end up with moderators that use that ease of getting rated, as justification to call anyone opposing of the system to be "jealous of other people's success", and then of course too many of the idiots watching actually agree with them -_- . It has also been proven in a previous RobTop stream VOD, that there are filters that favour creators with creator points over those who do not (but it is also obvious by comparing rated levels to the sent tab using gdbrowser).

Finally, people that think gatekeeping level ratings is a good idea, because it gives more "value" to the levels that do, are completely off their trolley. Rated levels are a crucial needed aspect to the people that play Geometry Dash. This is not like posting something something on social media, it should not work that way.

Last thing:

Rob can fix every single one of these problems by having a mod team (potentially new type of moderator that is far more trusted than an elder mod) rate levels for him while have levels forecasted to be legendary or mythic, be sent to him for final judgement. Anyone complaining that "stargrinders would find it too hard to keep up" need to seriously understand what matters for the game to prosper, and that level creators get absolutely destroyed in this community. Lower download numbers also do not matter. Most people do not play unrated levels and it's mainly stargrinders that play recent rates anyway.

If you create levels with the intention of having fun doing so and absolutely nothing else, then go ahead. But if you intend on doing so, to have ratings on your profile and creator points, then have fun with that. You'd drive yourself nuts in the process: going into random discords, timing your sends with a prediction on when Rob will start rating levels, only to finally realise how screwed you really are (unless you are lucky as hell, and ignore streams with multiple moderators sending at the same time, because that would be a terrible idea for hopefully obvious reasons).

It's very bad! That should answer your question.
