I've been tracing an ongoing pattern whereby large corporations seem to alter reach of tweets that are critical of the corporation, even when the tweets are factual. I've been critical of Cargill foods including exploring the link between the herbicides and antibiotics in their meat on testosterone. We're talking pubmed links, screenshots, etc. They seem to have blocked certain keywords like Cargill + my username and have selectively removed the most powerful tweets from Twitter search. On the selectively censored search results, the posts disappear from search during business hours, as if being hand picked by executives.
