Has anyone else noticed a shift in the ratings on here?

This may be me noticing patterns that don't actually exist, but I swear only a few months ago, most popular mangas/manhwas would be rated 9.0+ and now they are all much lower.
If this is true and anyone has any thoughts on why I would also love to hear your thoughts. But if this is untrue I'm just being silly don't make fun of me lol!
