The feeds on many public groups (seems to be a lot of buy&sell groups like "Windsor Buy and sell car's, truck's, van's, suv's") are filled with scams. Some are fake lost persons, dogs, children etc. What these scammers do is get people to share these fake posts because of an emotional appeal and then later on will often switch the pic to another scam promoting a fake house rental (for example) with a link that will ask for information and possible banking information. https://fullfact.org/online/silver-alerts-missing-pensioners-false/?fbclid=IwAR1Wz3R7VKCqCt4TbuR7WIl82mmO9L-jXmuTTKT-MVXsOxdG1VwYB8-VBR0
These scammers are also showing fake catalytic thief photos (well they are real, just from years ago), too good to be true jobs, fake company promotions for coupons from McDonalds, Coca-Cola etc, to get you to share for the same reasons I stated above.
Be mindful of sharing things from profiles that are fake and have little to no posts and no info about them (click on them to check before sharing) These scammers will often turn off commenting to avoid people like me spending my time warning other people, contacting them to make sure they are not scammed.
