[Off-topic] As I was reading the comments from a related thread, I noticed that the comments there can be tagged by the community. (See Alfman's comment, being tagged as "verbose"). That would be an amazing feature here in the Fediverse forums/link-sharers.
[On-topic] I wonder if Mozilla was buying time to retract its staff from Russia? Even if not, I respect their ability to revert a decision in a transparent way, and apologise to the community without sounding like a corporate "apology". It shows that they actually care about the principles that they're babbling about, even if they violated them with the temporary removal.
Re your off-topic aside, it looks more like that user has been tagged as verbose (whether that mean long comments or a high volume of posts isn't clear).
Yup, you're right - the tag is for the user, not the comment as I incorrectly said.
Either way it would be a neat feature IMO. (I'd be probably among the first being tagged "verbose", but I'm OK with this - other people could be tagged as "informative", "fun" etc.)
