Questions & Answers about Fastän hon älskar gatukonsten, vet hon inte vem som använder pseudonymen.
Why do we need the word som in vem som använder?
In Swedish, when an indirect question has a question word (like vem, vad, or vilken) that acts as the subject of that specific clause, you must insert som. Here, vem is the one doing the action (använder), so it is the subject. If she didn't know who you were talking to, it would be hon vet inte vem du pratar med (no som needed, because du is the subject).
Why does the second part of the sentence start with vet hon inte instead of hon vet inte?
This is the classic V2 (verb-second) rule in action. The entire first subordinate clause, Fastän hon älskar gatukonsten, acts as the first "block" of information in the main sentence. Because the main verb must come in the second position, the verb vet comes immediately after the comma, pushing the subject hon to the third position.
Since she is talking about knowing a person ("who"), why use vet instead of känner?
Even though the answer to "who" is a person, the thing she doesn't know is a fact. You use veta for knowing facts, information, or clauses starting with question words. You only use känna when you are personally acquainted or familiar with a person or place (e.g., Hon känner personen - She knows the person).
