People sending me random friend requests on steam

They are trying to reach you concerning your vehicle's extended warranty.

It's because you add people with high levels to your list and you leave your inventory public. The bots get their friends list and add everyone they have, and keep going trying to find someone to scam.

Edit: I wouldn't be so sure about where the accts are from, as you can list whatever location you want on steam.

Public inventory is why.

Oh that's a normal day if you got items for dota2, csgo, tf2 that are worth anything, they either beg or try to scam you.
Friendly advice, leave a disclaimer on your profile next to your name to leave a reason for adding u in the comments otherwise u ignore them. And just bang that ignore button for every one of them.

I have had people try and trade with me and my son for cards for items but when I say send me an offer they usually try and take every single card from me and give me a banana or egg form those clicker games - never did the trade but be careful

They’re trying to warn you about scammers.

That's happening a lot to me too. I try to accept everyone and asking the reason of the request. Sometimes they just want to chat I made few friends like that. They are nice people but sometimes just want to scam or for +1 friend. That's all. Nothing so special.
