Carping

Carping is what someone engages in when they post the same story to multiple places simultaneously. For example, someone might post a political news story to ten political debate groups on Facebook, hoping that someone will “bite” and engage with them. It has a tendency of wearing out audiences, and creating confusing threads as participants are challenged by having to choose which post to engage with.

This is usually done by people with a lot of time on their hands OR by people who’ve got access to some kind of automation that makes it feasible.
