What pretty much everyone said constitutes disrespect. However, also realize that some people consider anything they don't like disrespectful. This is the FGC.
I don't teabag my opponents or 'style' on them. Whether they're bad, whether they're good, whether they've annoyed me it doesn't matter. I just play the same. Do I mind if they do? Nope. Do I teabag them back if they teabag me? Nope. But that's just me. That's not "how it should be." That's just me.
In spite of this I have been called disrespectful and have received numerous death threats. It's the FGC bro. Your opponent will always find something to spite you with regardless of your respect towards him/her.
Apparently I'm not even 'disrespectful' for 'spamming' optimal combos anymore. I've gone past that, transcending above my peers through rigorous vigilance and am now Dante son of Sparda.
