There was an enormous post on prezi.com that was deleted around February 10th from that site. The post contained 100's to 1000's of social media anecdotal reports and video uploads from people who had taken the mRNA gene therapies (aka vaccines).
It was such a large amount of reports showing irrefutable proof of how severe and how many people had these adverse reactions, side-effects and deaths that it wasn't just removed from prezi.com, it looks like all archiving sites removed the prezi.com saved snapshots too.
