How do you know their country?

Their profiles and the lithunian guy because of his address i saw in paypal

It's not that hard to change your country on steam. Anyway just report them on steamrep.com

Bastards*.

This is a 17+ game, you can swear, it's okay.

it's obviously automated so each time you bump a trade you get several bots adding you.
easy to spot them because they are lv0-1 without inventory, so you just report and block them.

because people are jerks

for a year of trade I blocked about 300 scammers. "It is capitalism - baby!"

Yeah, pretty much.
People who either have no money or don't want to spend any set up these phishing bots. They look for anything of even remotely high value and add the person. Most of the time, since they're bots, they are rather easy to spot and block, etc.
However, these phishers wouldn't do what they do if it never worked.
There are dozens of people being phished everyday out of the thousands who were tried each day. I've accumulated about 250 Phishers over the last 3 months spent trading, and another roughly 100 people who were human, but phishers, nonetheless.
Sadly, phishers are a cancer to the tf2 trading society, and one that can't be easily cured.
To be quite honest, the only way this could've been avoided is if we got rid of expensive or even just plain items alltogether, and resort to a communism-like structure, and the problem with that is COMMUNISM SUCKS.
So, there's not much you can do about scammers other than block and report them.

Good luck and happy trading.

Well, there is a rather simple solution for this problem: make it cost money. Add one person: 1 cent. Send direct trade offer: 5 cent. Apply the usual 1 week to 1 month delay before you can actually spend the money you have charged to prevent cc fraud. Problem solved. Its just that the majority of people does not want to spend money on social features so if that would be applied now steam would be dead like uplay. But valve is very good in making us to want to spend money, maybe they find a way to solve this sooner than valve time ;-).

Hey, you're one of the lucky ones, some of us get like 20 per day. >.<

Just don't accept them as a friend, then..
