Your first mistake was your failure to credit OGS, the mods, and me with any common sense, which is why I mentioned that, with regard to the mods, in my reply. (And still you have ignored it, as we shall see later.) Instead of questioning your own understanding when you run into an apparent anomaly, you leap to a ludicrous interpretation that OGS is perhaps idiotically prohibiting the infilling of a single stone, the mods are enforcing it, and I am explaining it, all oblivious to common sense. Of course not (and yes, that should be obvious).
Your second mistake was your failure to read carefully enough to avoid confusion. Not only did item 1 specify “a series of self-atari moves,” but item 2, infilling, was also explicitly limited:
Did you miss the parenthetical “etc.” just like you missed “a series of”? Your example does have a purpose, so it does not fall within the definition of item 2, and yes, that should be obvious.
Yes, in many cases, or perhaps even in most, that is true. However, there are also a lot of abusive cases, where a more experienced opponent explains and/or begs them to pass and they ignore it or even jeer abusively in the chat.
Again, you leap to the ridiculous conclusion that mods are hammering them instead of teaching them. Do you really think no one else figured this out before you arrived on the scene? In most cases that are reported, the beginners are indeed instructed by the mod. They are not warned unless they continue in the behavior after being instructed. Make no mistake, malicious stalling is fairly common, and it often precedes score cheating. The cheat attempts to win by stalling (hoping for a frustration resignation), and if that doesn’t work, they score cheat. I have seen this pattern numerous times.
I have explained above why it should be obvious, but I think it is my tone that you really object to. Good. You adopted a hostile, presumptive tone, beginning with “What??” (note the screech of the second question mark), rather than making a neutral non-adversarial inquiry. When you take a tone with me, I slap it back twice as hard.
