Over the last few days there have been a series of users ( probably the same person ) posting answers which barely answer the question and then advertising slippers, jeans or some other junk.
One of the user accounts is https://security.stackexchange.com/users/1660/slippers
Is there anything that can be done to block this user from posting like blocking their IP for a while?
Here are some examples of the answers from these users I have edited the questions removing the advertising and flagged them as spam.
