I've noticed (and have done so today, in fact) that when I flag certain comments as No Longer Needed, they are auto-deleted right there and then, rather than requiring a moderator to delete them manually.
What are the criteria for comments being auto-deleted in this way as a response to being flagged (specifically flagged as No Longer Needed)?
As far as I can tell, it seems to only be on short comments below a certain character threshold (presumably because those are more likely to contain messages that are just "@Someone Thanks, fixed" or similar). Is it only if it's in response to a comment of mine (i.e. the "flagger" is the one who was being replied to)? If someone else flags such a message, even if the reply wasn't to them, does it still get auto-deleted? This is just me speculating on what the criteria might be; my main question is still the one in bold above.
