The point is that those two words are (in China) associated with being against the CCP. It’s kindof similar to “black lives matter”. To some, it’s a symbol of hate (with re. to the police). To others, it’s a symbol of fighting back.

Even if you assume those comments are written by Chinese trying to fight for their rights - and I doubt it is the case - there's still a fundamental difference: #blacklivesmatter was a tag that accompanied actual content. Here, there's nothing but the "tag", copy/pasted all over the place without adding any value.

Why is this particular "spam" being deleted? Youtube comments are full of similar "spam" that somehow goes undeleted.

They deleted you comment if it contained one of multiple "words" (compound words, short phrases).

It's like censoring someone commenting "It's FBI sponsored" or "Russian propaganda". Sometimes a view words in a context can say as much as a long sentence.

Also in Chinese thinks are a bit more complicated due to how different glyph can be combined and/or used in conjuncture. So I wouldn't be surprised if there is a situation where commenting with a single Chinese glyph is saying as much as a long sentence!

Chinese characters aren't magic. Putting two characters next to each other isn't fundamentally different from putting "Russian" and "propaganda" next to each other. You could write a sentence with just a single-character word, but that's not going to be more expressive than a single word in any other language.
