We've banned this account for evidently being a single-topic account that posts almost nothing that's within HN's guidelines. We've asked you before to observe the guidelines. Plenty of people criticize Israel's policies and actions in these threads, which is acceptable under the guidelines, but continuous shitposting like this has to incur a consequence eventually, otherwise the site would be overrun by it.
