I have been stopped from uploading more, what is wrong guys?

Nothing wrong. You've exceeded your submission limit for now.  Wait 8 days and try again later.

Focus less on quantity and more on quality.

Be more selective about what you submit.

Choose 2-3 of your very best assets to upload.

When they're approved, rinse & repeat.

Slow & steady is the best way to proceed. It prevents Contributors from overwhelming the review queue and causing long delays for everyone.
