Not really. I run several web applications on one 15$ VPS. Although the user count is <5. But I think it would need quite a lot of users for the resource usage to go up to a critical level.
Got my first computer with a modem in my bedroom when I was 14 in 1997. Meaning, I explored the emerging internet unsupervised. Of course, I watched a lot of porn.
I'm 40 now and still occasionally watch porn. Maybe once a month. So definitely not addicted. Also, I didn't even develop any kinks.
I've ordered several things off temu. You get what you pay for.
Meaning: don't expect quality.
It's fine for stuff like necklaces, wristbands and small things like like certain crafting supplies.
But I would not dare to order tools of any kind. Nothing you'd expect to last at all.
