I agree with you.

Maybe we can have better filters? More filter varieties? Custom filter where we can put: 
- Broad match "key words"
- Phrase match
- Exact match
to block/hide on our timeline? 
And we can have access to the blocked notes to verify if the blocking system is working properly (on admin we can choose to hide or not this blocked content) 

Possibility to check / uncheck some kind of algorithm that blur automatically possible adult content? And we can uncheck this to never blur anything, or to never blur a specific user (that we trust). On this "algorithm blurred image" people can vote on the "blur accuracy" ranking (bellow the image) from 1 to 10 (10 best - 1 worst). So blur system devs can use it to improve its accuracy, and people can use it to be sure if try to unblur it or not.

Maybe we can make our own Custom Trending + filter as well? For specific keyword or hashtag.

Sky is the limit. It's just a matter of patience and feedback from users and goodwill from developers.
