A user enrolled in the FortuneJack signature campaign, hence out of the reach of SMAS. FortuneJack neither employs a dedicated signature campaign manager (at least none I know of/publicly recognized), and I'm not sure if their campaign is ran automated (which would most likely mean posts not being read in any way before them paying for those).
Can't a mod or someone tell the campaign manager to control their campaigners and tell them to quit spamming?
You can report the user/campaign to hilariousandco (reference:
https://bitcointalk.org/index.php?topic=1684035.0) or to Cyrus, and check if the situation is enough for giving a warning to the advertiser.
