too many phising attempts lately

If you reported them then yes, they might get banned... Just don't add any strangers if you don't know any reason why they friend requested you.

Same here. They are bots, and, i heard, tons of people loose their stuff. Don't know how, because if you are using market, your steamguard should be enabled.
By the way, my friend want to trade your knife, add him staemcornrnunyitiy.com/id/gabentheking

I've had 1,681 market transactions and not a single phishing attempt.

if you add knife into market, its disaster, people keeps adding you, trying to beg, lowball and steal your account, I know that, so never want csgo knife again

what you can do is to just block/report them and move on. Im not quite sure if they are more in number but most of them are pretty easy to avoid.
Also keep in mind that just because an account is like 9 years old it doesnt mean there is zero chance of seeing it hacked/used for phishinhg or the account owner being a douchebag trying to fool people

Well, I had a few lately, sadly Steamrep doesn't care and I think Steam support does neither. Fortunately enough, these phishers are stupid.

My cousin put a knife on the market asking a reasonable price. People kept asking him to sell it to them for like $60 (Average selling price was like $200 and he put it on sale for like $180) and they wanted them to add them on enter random website. And they wanted him to go first on the trade because they didn't trust him. I really don't know how people fall for this bullshit.
