Americans Will Now Be Required To Identify Ukraine On A Map Before Posting Opinion On UkraineU.S.—A new social media initiative will require Americans to identify Ukraine on a map before being able to post an opinion about Ukraine on the internet.
Before American internet users can tweet or create a Facebook post demanding immediate U.S. intervention in the foreign dispute in Ukraine, they will be required to click the country on an unlabeled map of Europe.
"It looks like you're trying to tweet about Ukraine. Please locate the country on a map first," reads Twitter's pop-up warning that displays when someone tries to tweet about the country. Facebook's algorithms will filter out posts by boomers filled with U.S. flags and eagle emojis demanding we start World War III over the issue unless those boomers can accurately identify where Ukraine is on the map.
"This won't, of course, stop all of the bad opinions from getting out there," said one analyst. "But it should filter out something like 98% of the uninformed rhetoric on the conflict. And, in some small way, it will increase American knowledge of geography, which is never a bad thing."
Indeed, one recent study found that more Americans could accurately point to the different regions on a map of Westeros than could identify "those lame European countries" that actually exist.
Report: Everyone Who Adds Ukrainian Flag To Profile Pic To Receive Nobel Peace PrizeNORWAY—In thrilling news for supporters of Ukraine on the internet, the Nobel Committee has announced that everyone who has bravely added a Ukrainian flag to their social media profile will now be awarded the Nobel Peace Prize.
"Every year we scour the world for heroic leaders and freedom fighters who have contributed to the cause of peace," said committee member Bjørn Jørgensen. "Well today, those heroes are all of you—the unsung heroes of social media who have taken the time to add a Ukrainian flag icon to your profile pic. This is the kind of thing that stops dictators like Putin in their tracks."
According to the Nobel Committee website, internet users will have until March 1st to add a cute little Ukraine flag to any one of their social media profiles and qualify to receive a peace prize medal in the mail. Those who do not provide their shipping address will instead receive a cool little Nobel Prize NFT instead. Awesome!
"Today, the Ukrainian people thank the social media users around the world for standing with us," said Ukrainian President Volodymyr Zelenskyy while chomping a cigar and loading his belt-fed automatic weapon with more ammo. "We wouldn't be alive if it weren't for you."
UPDATE: According to sources, the committee is now reconsidering this idea after problematic podcaster Joe Rogan added the flag to his profile pic.
