If it's a Public Group, yes, friends can see you joined. If it's a Private Group, your posts and activity are visible only to other members.
You likely skipped the membership questions. Admins use these to filter out bots. Make sure to answer them to get approved faster.
Filter by your City and select "Business" or "Buy & Sell". Facebook is the king of local marketplaces and second-hand items.
Go to the group header, click "Joined," and select "Leave Group." You will stop receiving notifications and seeing posts in your feed.
These groups don't appear in Facebook search results. You can only join them via direct invite links like the ones hosted here on Neargroups.
Some "Social" or "Singles" groups exist, but exercise caution. Facebook is not a dating app; never send money to anyone you haven't met in person.
Join local "Community" or "Small Business" groups. Don't spam; instead, offer value or advice to build trust before pitching your product.
You might be blocked by the admin, or Facebook may have removed the group. Try a different link from our "New Groups" section.
