I ignored the guy (along with some of his aliases) a long time ago. He's a total OCD case but doesn't realize it. He actually had over 10,000 posts (last time I checked), and it was kind of sad watching him have conversations with himself through his aliases. My guess is that he went all-in on RIMM a while ago, and lost it all. He's bitter on RIM and everyone else that wants RIM to succeed. It appears he's made it his mission in life to use this board as an emotional outlet, so I just blocked him to filter out the noise. It's best to ignore this sort and move on.
No he has been very wrong. Bears said rim would trade between 4 and 5 after earnings report. Thats like 60 to 100% wrong. In fact when a bear is a 100% wrong, that is actually worse then buying rim at 140, and riding down to 6.(thats only 96% wrong)
