Something seems wrong with your sentence.

Hi, MM

Do you think that he is what is known as a hacker is wrong ?

.
No, but what goes in the other space?
.

I presume nothing…
He likes to show off on the Internet and attack websites is a standalone sentence in my book.
Do you think it would be better to write He likes showing off on the Internet and attacking websites ?

I’d say that’s basically six of one and half a dozen of the other, Alex. :lol:
.

Gotcha :wink:

sorry. It’s like this:

He is____is known as a hacker — he likes to show off on the Internet and attack websites.

A. who B. what C. that D. which

Ah ha! But an m-dash is written as two hyphens (and of course, not dots), vaok, with no spaces:

He is_what_is known as a hackerhe likes to show off on the Internet and attack websites.

Thank you MM, but a lot of people choose" Who", I don’t know how to explain why it is not right. Can you help me?

.
Because it is a definition. What is a hacker? It is someone who likes to show off on the Internet and attack websites.
