There may be an age or generational explanation for this, but I especially notice this behavior on Reddit while not nearly as much here on Lemmy (though maybe that’s also a mater of implementation).
It seems many are so quick to assert overly-confident positions, but then hit-and-run with some smarmy remark at even the slightest challenge, then quickly block. Like, not even crazy stuff. Just basic, civil disagreements. I can pretty well predict when it will happen, and it always feels like such a petty ego-sparing fingers-in-ears denial thing to do, and to me if anything shows they were not very confident in their views being challenged.
I think I’ve only blocked a handful of people over a decade who were actively spamming, stalking, or spewing extremely hateful rhetoric and I just reported them simultaneously. You have to cross a pretty extreme and irrational line for me to do that.
The reason I ask is to see if I’m missing something; to better understand the mindset of those who do.
If you’ve previously had the experience of reaching out to someone politely in good faith about a problem with your purchase, and they really were a scammer and responded “haha get fucked loser” and blocked you, that’s a mentally damaging interaction. You made yourself vulnerable and got taken advantage of. Not just once for buying from a scammer, but twice for then politely asking the scammer to help you! And that feels awful - as if the scammer “won”, and you are a sucker who didn’t even realise you’d been scammed.
That is why people are quick to go on the offensive when they suspect they’ve been wronged, because they’ve been hurt before and want to try and claw back some small measure of pride by saying effectively “Okay you scammed me, but I’m not so stupid I don’t see it, and I won’t make myself vulnerable to you.” - that’s what the message and block you received really means, if you unpack it.
I would be so much nicer if things weren’t this way, and we could assume the best in people. With honest sellers such as yourself, it would even lead to the problem getting fixed! But there are a lot of scammers out there, so I understand the psychological “why”, even if I don’t like it and try to never behave that way myself.
