[Air-L] Looking for literature on spam in online communities

Hello all, I’m beginning a project about the research and practical implications of spam in hashtag-based Twitter communities focused on education. I’d appreciate any suggestions for any work on spam, especially conceptual work (e.g., definitions of spam, taxonomies of different kinds of spam, etc.), since that seems to be harder to find than work on spam detection (though I’m also interested in that work as well). Thank you!
