The close as spam option never existed on SU as this is under the flag option available to users with 15 or higher reputation. This option will dock a 100 reputation points from the offender when 5 votes are received. As per JeffJeff this is intentional as it is meant to be removed across the trilogy.
With regards to this particular question. It had been flagged by 2 users, the question deleted and user account destroyed as spam. Therefore only 10K and higher users will be able to follow the link.
