“May” is the key word in that long sentence. bioRxiv certainly does not review content of submissions using the standard definition of the word “review”. They may scan for style and general content type—for example rejecting reviews.

But I agree with the parent comment that these archives are extremely valuable.

I disagree that informal community comments are of much critical value. In most cases twitter comments and micro-reviews are relatively trivial and are usually based on quick reads rather than deep perusals.
