[ba-poker] Is being obnoxious a tell?

["Uncle Roger" <rogerc22(deleted the rest)>]

Now that I'm playing a bit more online, I'm trying to learn about online 
tells.  So I was wondering whether being obnoxious is a tell.

There are many kinds of obnoxious players, so let me narrow the field.  
There are some players who sling insults at  players who make loose calls, 
even when they themselves were not on the receiving end of a bad beat.  
That's who I'm talking about. They are making an affirmative effort to type 
in stuff intended to make other players feel bad, even when it is against 
their own long-term self-interest and they are not emotionally involved in 
the hand.

It seems to me that these players are more likely to be selective and less 
likely to be fancy.  They are not necessarily great players, but you can 
count on them not to have a straight in early position when the board reads 
7-6-3.   You can generally trust their check-raises to stand for what they 
represent.

It also seems likely that they would be more vulnerable to tilt, but since I 
mainly play in tournaments I haven't been able to verify this hypothesis.
