if your account is established enough not to trip whatever crude fraud algorithm they have, ebay is an extremely convenient and efficient way of buying and selling stuff. maybe its because ive done it for a while so im used to it, but im always suprised when people complain about ebay. i think you get into real trouble if you expect it to be 100% perfect, but if you just accept that every now you might get screwed and dont put all your eggs in one basket, it works very well.
I'm not sure account lifetime is a factor - on an old account I remember getting (very obvious) scam messages sent to me from long-established accounts that have presumably been compromised. If anything, account lifetime might work against you if you log in with an IP address or browser fingerprint that's too different from the account's history.
the problem is it can happen to anyone for just about any reason, you've just gotten lucky. meanwhile people who don't even use the platform as much as you get banned much quicker.
