Has there been any hint that the PRs were not being reviewed? I haven't read any suggestion of that in the direct chain of replies.

Sure. Look not to the replies, but the top of the thread. The 'hint':

> " ... can't they read my PRs?"

I know one really good way to answer that. The requirement for the question suggests the same for review.

You're misreading it. Reading the speaker's PRs is presented as an alternative to talking to them, in the same way that if Alice and Bob were arguing whether song lyric sites should exist and Alice asked "can't they listen to the song?", it would be a rhetorical question and would not indicate that Bob did not listen to the song he wanted to read the lyrics of.

Hah. Disagree, don't care to continue. Have fun/take care.
