Black Widow might make this a place for criminal activity? (4,3)

'make this a place for criminal activity?' is the definition.
I know nothing about this answer so I can't tell whether this works.

'black widow' is the wordplay.
'black' becomes 'dark' (synonyms).
'widow' becomes 'web' (I can't explain this - if you can you should give a lot more credence to this answer).
'dark'+'web'='DARK WEB'

'might' acts as a link.

Can you help me to learn more?
