Revise / rewrite sentences that use the phrase "referred towards"

Comments by Mike <mike_mp@zzzcomputing.com>:

"Referred towards" is not correct English and can be replaced directly
with "referred to".  However, this then introduces a dangling
preposition to sentences which I don't think is appropriate for this
style of writing.  So instead, use phrases like "known as",
"references", "to which X refers".

To help me identify dangling prepositions I made use of ChatGPT,
here's the log of how that transpired:
