Description:
Sadly, he is my friend in the real world. Since I added him he annoyed me for a dirty Soldier hat. I gave so he could shut up.
Weeks ago, he tried to sell me a Scout hat for some unusual high price.
Today, as you can see, he begged me for my Demoman hat.
Also, he is frequently asking me to trade, just to show his drops or sell me crappy items.

um I don't think you can report someone for begging for hats

This doesn't involve any sort of scamming as do I believe this belongs off of SR.

Hello there! This doesn't seem like a scam report. All you have to do is ask your friend to stop asking or show him the ways of trading.

Hi there.
You currently have no proof to show an actual scam took place.
Although I am not a Steamrep staff member and cannot make jugdement calls, I can say that it's highly unlikely for your friend to get marked for begging, sending you trade requests or annoying you.

Your friend is not scamming, he's just being annoying. They're two whole different ballparks.

He's not scamming or anything, just delete him or block him.

He did specify that he (the begger) was his IRL friend, so I don't think that will do much.

Oh, I see what you mean, like the begger could call him and etc.

As others have said, this isn't a scam- this is just a friend who is a mooch.
Since you are friends with him IRL, there's a few options to get him to quit. The easiest and most sure-fire way to get him to stop is to get a group of friends together to hang out, then bring it up and your other friends will back you up that the moocher should stop.
Example conversation:
"Okay guys, seriously, Joe here keep bugging me on Steam to give him items. Like I already gave him some but he just won't quit. Seriously, Joe, what's the deal?"
Friend 1: "Yeah Joe, that is not cool. Go mow some yards or something and get your own stuff."
Friend 2: "Why u so beggy, Joe? LOL"

As long as you keep it light, it should discourage him permanently without causing any damage to your friendship or embarrassing him in front of the rest of your friends. Keep things in a friendly, jovial tone and talk with your other friends in advance so they know to also keep it friendly while backing you up on it.
