The concept of mass in special relativity is indeed confusing, bugt that does not eliminate need for it.

It seems to me, that there might still be some sort of on-going debate about this relativistic mass thingy among the real physicists. I'm not a real physicist, but you certainly seem to be, so I'm very likely just to take it easy and just believe whatever you're saying...
But moving too fast just won't turn you into a black hole, in any frame of reference ('cause if it did happen in one, it'd had to happen in all the others, too, right?), that was the key point I was making, I guess...

Your response to llatpog regarding appearance of particles outside the event horizon is correct.

I don't think debunking Einstein was the point in those links at all, more like on the contrary, I would say. I don't remember exactly what it used to say there, when I first linked the page, but currently it seems to be much more "pro-relativistic mass" than it was back then, in January of this year, I guess. Here's the same link again, though the contents of the page have now changed a bit:

Says there, that the concept of relativistic mass is still very "useful". OK by me then, I guess; let those who calculate these things for work, on a daily basis, use it if they want to...
