Does Redfin remove listings?

[Jeb Brilliant]

I'm looking around Redfin this morning and notice some nice looking properties that are priced for a quick sale and I feel like they should get snatched up quickly but Redfin has them listed as being on there for 70 days, 200 days so on. Does anybody know if Redfin tends to forget to remove sold homes? I feel like many of these should have sold already and they just get left up.
