evidence: The report from Full Fact (via The Guardian), which is an independent, fact-checking charity in the UK, has gathered data and examples picked up over the past year during its studies of online misinformation. Overall, Full Fact found 1,200 examples of hoax posts in Facebook groups during the last 12 months, which it says is likely to be "the tip of the iceberg". [...] You can also run a post's text through a quick check by pasting it into Facebook's search box in the top-left corner, and seeing if it's been used elsewhere with different images. For local groups, Full Fact also says it's worth checking the language to see if it doesn't sound like it's from your region. While Meta has introduced new tools for group admins – like the ones it announced in 2022 that let them automatically approve or decline member requests – and also partnered with 90 independent fact-checking organizations (including Full Fact), there's clearly still an issue with hoax posts. So it's well worth arming yourself with the tips above, and double-checking those posts about missing dogs or serial killers if you're a keen user of Facebook's otherwise handy groups feature.
