Who is replaced by whom when it follows a preposition.
sort of. in practice i guess that's how people use it, because it's a dying word. but if you want to be "grammatically correct" about it, it can be tricky depending on word order. the rule of thumb that actually works in any case is "if you replaced the word
who by a third-person pronoun, or if you directly answered the question by rephrasing it as a statement, then would the pronoun be
he/she or would it be
him/her?". he = who, him = whom. who does it? he does it. whom is it done to? it is done to him
the thing about
that instead of
who, i think i read somewhere that there are purists who consider it wrong to say "someone that does something" and it should always be "someone who", but afaik that's a minority among the "experts" on the subject, so it's a matter of regional variation and personal choice/style
