That was, by any standard, a d*ck move. If you don't want people running your kernel, don't help. Tricking users into wiping their drive, from an account with good TMO standing is the height of d*ckery.

It is not up to you to decide who is worthy of touching the holiness that is their device. We all learn piece by piece.

If whoever copied your signature and ran it, fine. But posting that as a fix (even two posts down after the explanation) is out of line. I don't believe you read every thread, completely, every time, no mistakes.

Remember that not everyone have your settings. I, e.g., have about 50 posts per page, and every time someone says "back on page 4" I want to strangle them. I don't. Maybe he/she just missed the post on the previous page. Maybe he's tired, maybe, you know, his phone doesn't work.

If you feel he shouldn't be in -devel or -testing without being a guru, say so.

Next time you think this is funny, remember that there are times we need help. When you walk into a hospital office saying "help me, I've been poisoned", a doctor should pee in a cup and have you drink it because you shouldn't be drinking stuff you don't understand and you deserve even more problems.
