A quick look at your commenting history suggests that this was the case here. We warned you repeatedly, in fact:

That's the sort of history we do ban accounts for, for what should be obvious reasons. Also, please don't create accounts to break the site guidelines with and please don't routinely create accounts, which is itself against the guidelines: https://news.ycombinator.com/newsguidelines.html.
@dang Is that so? Why?
If you think a [dead] comment would contribute positively to the conversation, you can vouch for it, in which case it will become visible to everyone once enough people have vouched for it.
Once an account has an established history, we say publicly that we're banning it: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
