I like how they justify it by claiming that the tweets were automated. How so? I saw lots of real humans complaining that their tweets were blocked.

I think the logic goes like this: "We wouldn't tweet that. Nobody we know would tweet anything like that. Therefore, this is not from real people." Maybe the Twitter employees need to get out a bit more, perhaps taking a lengthy visit to rural Oklahoma or West Virginia.

There may be some feelings of guilt here. To deal with that, just claim that the tweets aren't from real people.
