I'm sure many users have noticed the annoying spam messages that get posted in the comments of every article that reaches the main page. So why not just create a blanket filter for the words "wholesale", "retail", "handbags" and anything else the stock posts contain? Since they're most likely being posted by a bot, genuine users can still use the or tags if they want to post a filtered term.
But boys will be boys and girls have those eyes
that'll cut you to ribbons, sometimes
and all you can do is just wait by the moon
and bleed if it's what she says you ought to do
