[Grammar] text appearing on the screen demanding users to send money

Ransomware is often transmitted via email or web pop-ups, with infected computers being locked up and text appearing on the screen demanding users to send money within certain amount of time, otherwise the data on the computer will be destroyed .

Hello, everyone.

I wonder whether ...text appearing on the screen demanding users to send money is grammatically equal to ...text which appear (or which appeared) on the screen which demand (or which demanded) users to send money.

Therefore, could I put an infinite number of "which" in the phrase? just like text which appears on the screen which demands users to send money which A which B which C....

Thanks!

I don't know why you switched to the past simple. Also, be mindful of subject-verb agreement when using the present simple (e.g., "which appears", not "which appear").

No, it would not be a good idea to use "which" like you suggest above.

Because I don't know which tense I should use.:-?

Also, be mindful of subject-verb agreement when using the present simple (e.g., "which appears", not "which appear").

I looked up the word text in OALD online:

[uncountable] the main printed part of a book or magazine, not the notes, pictures, etc.

[uncountable] any form of written material

[countable] the written form of a speech, a play, an article, etc.

And I chose the [uncountable] definition.

Oh, I have just known that uncountable noun uses a singular verb.

No, it would not be a good idea to use "which" like you suggest above.

You mean it is grammatically correct, but sounds unnatural, Is it?
