Maybe so but you can't assume that just because someone is doing the same thing for 15 days in a row that they are a bot. There is a female lalafell on wutai that everytime I see her, is pounding on an anvil (armorsmithing). So should I assume it's a bot? The funny thing is, if you talk to her, she will respond. So clearly not a bot.
I am not defending SE, as you claim, I am just saying, not everything is black and white, and that they have to be 150% sure that the person is in fact bot, and they aren't making a mistake.
