Do you want the details? The first thread of some weeks ago was about how the Korean government started using blockchain for their own purposes. I was deeply baffled when I saw it deleted, while value-less new comments about e.g. Satoshi's identity stay.
This is a bitcion forum. If it was a thread merely about blockchain tech used by the Korean government in Bitcoin Discussion then that's probably why it was trashed. Unless it's related to bitcoin then it'll be trashed or moved into the appropriate sub.
And today? I started a thread discussing the new Metronome coin and its unusual sale strategy. I even got replies. What was my sin here? Is a decreasing price sale more meaningless than the n-th post about how great or horrible BTC is without any argument, or often without any grammatical structure? Was my sin the fact that I mention I'll buy some Metronome?
Earnest replies appreciated. I'm a noob on the forum trying to discuss what I deem to be serious questions and points, because this is how I view this whole story. I have some respect for what is going on here, so I'm baffled by my posts seemingly being considered pointless and insulting, while I'm kept in the dark as to why this is so.
Did you post it in Bitcoin Discussion? If so, then discussion about alt coins doesn't belong there. Threads containing ref links or just 'buy this coin' threads are also trashed.
