No, being saucy is fine, and people much more disagreeable than you (cough) seem to thrive here. I can't see why you were banned, but I asked, because that's weird.
I think it's pretty complicated, actually. I've lurked here for years but only made an account within the last year. In that short time, I've said arguably worse things than you have (though not with ill intent; I can just be abrasive and opinionated) and as far as I can tell I've not been hellbanned yet.
It probably helps that I'm a "nobody"; I'm not a member of the startup culture, just an outside observer and occasional commentator. If it's true that politics are a factor in bans and heavy-handed moderation, then I can understand (though not agree with) you being hellbanned for what are fairly mild comments as judged by an outsider like me, as you are a member of the startup club.
And I hate to say it, but misogyny might even have played a role in it. I have zero evidence of that and it's not meant as an accusation, just that it's a remote possibility. It's a real problem in just about any internet based community, and I really doubt this one is immune to it.
