Thomas Poell researched the influence of social media on the 2010 protests of the Toronto G20 summit . In the article , he focused on identifying how each social media site was used independently , and then how they were integrated together . The sites analyzed were Twitter , YouTube , Flickr , Facebook , and an open publishing website . What he found is that each site is used differently for social media activism . While this kind of activism was originally looked at as a way to promote causes and encourage long term focus on the issues , Poell found that sites like Twitter and Facebook tend to do the opposite . Posts center around photographs and videos of action during protests and rallies , not on the issues that are being protested . This would be an example of hot media , because the user can scroll through photos or watch videos without being otherwise engaged , instead of cool media where the user has to be more involved . Additionally , because activists are using sites they do not own , the social media platform actually has more control over the information being posted . For example , Twitter no longer allows unrestricted access to all posts made with a certain hashtag after a period of time . This seems to mean that the issue being highlighted fades over time
