On Facebook, a search for an AAPS article on vaccines, which previously would lead directly to the AAPS article, now produces search results...
The AAPS are an odd bunch, who campaign against "evidence-based medicine" (yes, seriously), and also claim AIDs is not caused by HIV, abortions cause breast cancer, and Bill Gates spreads coronavirus through 5G (probably).
And it makes sense to remove them from facebook, as it appears even seemingly intelligent people can become enthralled by the 'secret knowledge' offered by these fruitloops.
