The abuse page http://wordpress.com/abuse/ has no options for viral hoax entries, such as https://wausaunews.wordpress.com/2014/01/18/big-hospital-finally-telling-the-truth-about-cancer-johns-hopkins/
The options for reporting abuse are the following:
- This content is spam
- This content should be marked as mature
- This content is abusive
- This content promotes self-harm/suicide
- This content infringes upon my copyright
None seems to cover viral hoax, which seems very abusive because it promotes disinformation and farms clicks on ads.
