You are blowing out the margins of the page. A few hot pixels at ISO 3200 is not the end of the world - most cameras have some at high ISO. Nikon may be able to map them out, though I've not had that done with the low-grade cameras. I think you have unrealistic expectations for a cheap camera.
My D700 does the same - I have a few hot pixels here and there - it's no big deal really. I may have them map them out when I send it in for AF calibration, but I've been living with it for the last 9 months without worries.
The magenta around the edges looks like thermal noise - heat from the electronics creeping in during long exposures.
All looks normal to me. Don't worry about a few stuck pixels here and there.
It looks like you only have two hot pixels and two questionable hot pixels. 4 hot pixels in all. Its not a big deal. This is normal. I've had hot pixels on all of my cameras.
Lightroom and Photoshop ACR maps them out and removes them automatically when you open the image up. I can't comment on how other image editors remove hot pixels as I'm pretty much just an ACR junkie.
Bottom line is this is normal and there is nothing to worry about... if you have the right tools
Coming from a large software company located in Redmond, WA I would say camera tester is highly appropriate. Testers are trained to break things to use things in ways the developer didn't think of. Camera Tester did exactly what any great tester would do!
Seriously though, I hope you get this squared away as being down a camera has to be a bummer.

This guy is actually following your business model as well. 1. Throw the result out there without giving much of an effort to identify or correct the problems. 2. Let the public outcry guide you in making some minor corrections as you prepare to throw the next thoughtless result out there. 3. Profit!

I like the method of taking a shot of your LCD monitor; auto-level and you'll see the spots as bright as day
Don't recommend it if you're obsessive over dust spots though

Taking pics of your lens cap will get your ridicule from many places. Take a real pic. Any 100% dark pic will show the worst of a sensor, especially at super high ISO. If you had that much noise in a regular pic in decent light, then yes, you'd have a problem. But I highly doubt that's the case.

Theres nothing wrong with your camera, go away. And protip, to check for sensor dust, TAKE A PICTURE OF YOUR COMPUTER MONITOR. Its white and even, duh.

I've got a stuck bright red dot in every photo, and I really want it to be gone. That's not normal, and it happened only after I cleaned the sensor. Is there any way to fix this? Please help me, give me any way to make this dot gone. Please. Thank you

My brand new D300s had a couple stuck pixels. Almost all of them will if you really look for it. Adobe Camera Raw gets rid of it on its own every time I open a file! It's one very, very tiny pixel.

Not really. You can shoot raw, and convert in LR, which automatically cleans most stuck pixels. If you send the body to Nikon, they can map out the pixels, which effectively disables them. Once they are stuck on a color, they are never actually fixed. It's highly unlikely that these pixels would actually cause any visible defect in an image. As others have said, ISO 6400, 2minute+ ss with a body/lens cap on will show noise like that on any sensor. The later shot you posted does show some problem defective pixels, but again, doesn't mean you'll ever see them in an actual photo. I see about 4 bad pixels, I wouldn't worry about it unless it's causing a problem with your shooting. Instead, just enjoy the 12,212,220 pixels that are working properly.
And the pixel problem popping up after cleaning the sensor is a complete coincidence. Sensor cleaning with your shirt can cause problems, but damaging individual pixels isn't one of them.
