Citizens also need tools so that they can check for bot behavior. Some exist, but to be most effective they should be integrated with platforms to make checks available with one click.
Starting points are SocioViz and OSoMe both of which are very useful in spotting co-ordination between accounts driving campaigns. If tools like these were integrated into platforms to execute, cache and visualize queries with a single click, social media manipulation would be far easier to spot.
Even simple changes such as paging follower lists (to spot bot stuffing) and displaying “who trended” information for popular hashtags. Would help.
