Are there any? There's been a bit of spam lately - I've commented in the relevant posts, as there doesn't seem to be a way to report the posts / accounts.
Spam posts get removed eventually; it's just that none of the moderators here are full-time, and it might take a few days before they get to it.
There's a thread in the "Site Announcements and Feedback" forum where people post links to spam posts they've noticed, but after a few weeks where the mods have spotted it first, the post has been locked for inactivity. It might be worth creating a new post there if you see more, as I expect those responsible for the site are likely to check that forum more regularly.
