I can't see anyone falling for that crap on here.
I have several chacters with bears and their pupils (they have many) have no better chance of getting a bear than any other brute.
If you REALLY want a bear, use a script to create a few hundred brutes and then check them on a prediction tool to see if you'll get a bear (or wolf, or whatever else you want). It's an actual working method.
Your 'tip' is just spam to get pupils. There is NO basis of fact in it.
In fact, you didn't even manage to spam properly. You're supposed to mention about having to pupil you on a fresh IP to increase your chances of getting the bear (ie. to make sure you get XP) etc etc yadda yadda yadda .....
Search teh 'net. It's been posted a million times before. And it doesn't work.
