But Lincoln said (in Wanheda Part 1) that Luna couldn't take him and Octavia in because she was in hiding and didn't want to risk the attention. But in S1 and S2 Lincoln said that Luna could take them in, so that must have meant she wasn't in hiding then.

If Luna was known to house runaways/criminals/traitors she would have been executed for treason. Maybe not by Lexa but no other Grounder would put up with that. I think the kill order for Lincoln is the reason that Luna wouldn't risk being hunted by Lexa.

As for housing murderers, maybe not. Maybe just runaways/traitors/banished crminals from Polis just like Roan (Emerson might be there).
