Your post was likely deleted because the comment you were responding to was also deleted (likely because it was insubstantial) and your post didn't add anything else to the conversation. I don't see why you're acting so surprised by this.
Right so a post like that would be deleted, but yet I see people calling each other the most disgusting things imaginable with NO relevance to the topic at hand and those comments are not deleted? (on other topics than the HyperStake topic)
I remember several months back on the HyperStake topic there were a few posts about being superhero's, it went on for a few posts and then back to discussion about Staking and other boring conversation. Was it offensive to people? no, and it contributes to the community and
self moderated topic in that it keeps users engaged with the community and fosters new ideas.
How about the GAW service discussion thread? I see lots of minor posts there. How about the tnt exchange (likely scam) thread recently? That was renamed as a giveaway thread and wasn't taken down as fast as some of these comments.
Edit: I do understand this is a private forum but mods should also understand that people do not appreciate having their posts frequently deleted if not meant to be offensive or spam.
