Twitter flags European Journal of Medical and Health Sciences website as 'potentially spammy or unsafe' after user tweeted link to its study about efficacy of Ivermectin as a treatment for COVID-19. User's replies to tweets about coronavirus vaccination also blocked and deleted: Following a user's tweet of a medical journal study, which reportedly proves the efficacy of Ivermectin as a treatment for COVID-19, Twitter flagged the entire medical journal's website which the study originated from "as being potentially spammy or unsafe." Thus, when shared on Twitter and then clicked on by users, the link to the European Journal of Medical and Health Sciences (EJMED) website produces a warning from Twitter indicating the URL may be unsafe. "The link you are trying to access has been identified by Twitter or our partners as being potentially spammy or unsafe, in accordance with Twitter's URL policy," the warning page stated. It added that the link may fall under any of four categories listed by Twitter: "[M]alicious links that could steal personal information or harm electronic devices, spammy links that mislead people or disrupt their experience, violent or misleading content that could lead to real-world harm, or certain categories of content that, if posted directly on Twitter, are a violation of the Twitter Rules." The unsafe link warning prompts users to return to Twitter, while providing a hyperlink in fine print at the bottom of the page allowing users to click-through to the protest's website. Per Twitter policy the platform requires the removal of tweets that include "false or potentially misleading information" about "preventative measures, treatments/cures, and other precautions" related to COVID-19. The user, who goes by Tickerguy on Twitter, initially posted a link to the EJMED study alongside the following statement: "Oh, so pre-exposure (vaccine-style) prophylaxis with Ivermectin doesn't work you say? The drug is just an 'animal wormer'? Perhaps you should read this and then shove it up your doctor's A**; these GHOULS have killed 150,000 Americans on purpose." In a separate tweet Tickerguy said one of his replies to a tweet about a coronavirus vaccination clinic, which mentioned the alternative treatment method, was blocked. Twitter also deleted Tickerguy's reply and blocked all other replies. "There is a $2 prophylaxis that works just as well," noted Tickerguy's reply to the vaccination tweet. His reply also contained a link to Eastern Virginia Medical School's recommended COVID-19 protocol, which included Ivermectin as a potential therapy.
