I'm not 100% sure I belong here (I'm respectful...But I'm also a bit of an opportunist. You trip, I smash), but I try to be respectful when Smashing.
my rules for being a respectful smasher are:
Under no circumstances do I put the other players down before, during or after a match. A little taunting is fine. After all, it's a fighting game, but I DO NOT attempt to make the other players feel inferior.
I do not edgehog recovering opponents unless they do it to me first. (I'm looking at YOU, SEPIAN!).
I do not deliberately go for a 0% kill with the Dragoon. Unless they're the only player left, or they're far in the lead, I don't try to go for a cheap kill. (but lifting unsuspectin opponents offstage with the landmaster at 0% if fine by me.

if they're quick and realize what's hapenning, they can escape)
When up against a much weaker player, I do not own the living snot out of them. I will tone down my game, and try to help them learn their game better.
If my opponents are distracted by something in real life (cell phone goes off, spider lands on their face, etc), I stop pursuing them until the distracotin it gone.
by the same token, I do not distract my opponents in real life with any physical contact.
When pausing, I announce that I'm pausing before I do. When unpausing, I move the screen to show everyone, and do a countdown.
I do not cower. Fleeing combat to get some breathing room or to grab an item is fine, but constantly running away and letting the other players kill my opponents for me is not in my strategy book.
Blasting human opponents off the stage by juggling helplessly them with the beam gun is only a strategy I use if they are waaay in the lead. (or if they're cowering just offscreen...then they're practically BEGGING for me to do it.)
I don't go after taunting opponents just because they're vulnerable (I.E, if there's another player that's closer to me, that isn't taunting, I'll go for the one that's closer). However, if they're in the middle of a fight, and they taunt right in front of me... I WILL hit them.
Whether I win or lose, it's all about the fun. it's not about being better than the others.
lastly, even if my opponent beat me, or used a cheap strategy, I will refrain form cussing him/her out.
And those are most of the rules of respectable smash that I live by
