If I may take the risk of joining @Demmedelusive in potentially being “disappeared”, I would state that the “today” qualifier wasn’t really needed. 
You make it sound like there’s loads of closed topics today, but I only see three.
The many was posts.
From my viewpoint I thought I’d just moved a lot of posts about flagging out of topics that weren’t about flagging.
Just about every flag is followed with a “I don’t know why that was flagged” post. Which is sort of obvious unless the poster flagged it. These are just getting out of control at the minute.
Ironically, I nearly put them all here since they would be vaguely on-topic 
Nothing is ever deleted though. It’s all just pushed aside somewhere.
No matter the forum, no matter the subject, moderators always get a hard time.
Unless you see every single post, every edit, you’ll never get the full picture.
They do it for free. Cut them some slack.
From my perspective, if a comment doesn’t break the rules, it shouldn’t be hidden. It’s fine to merge or move posts to relevant topics, but just moving them to a hidden archive section doesn’t really help anyone.
How the place runs isn’t up to me at all
I know what I’ve been asked to do and I do it. When I have time.
If I cross a boundary somewhere or get it wrong I suspect Monzo will moan at me.
Not sure if this is aimed at me, but surely you’re making the decision about where to move a post? If Monzo is dictating you move all off-topic posts to some hidden area, then that’s a different thing, but without being rude and all due respect intended, I don’t see other members of the Coral Crew commonly acting in this manner.
Not rude at all.
In part I’m trying to avoid every thread being opaque to newcomers (I know, I know) just because it’s full of flag chat. Maybe it just annoys me more than other people.
That’s fair enough. As has been said, you volunteer here and moderation can be a thankless task as I know from personal experience, I just think there have been times beyond the flagging posts where discussions have been needlessly shutdown which is disappointing.
With that said, I’m going to draw a line under my comments as I don’t want to risk coming across as personally attacking you which would never be my intent. 
Oh mine always get flagged it’s annoying
Yes but why should every flagged post derail the topic onto the justification of flags? What’s the point? There’s nothing we can do about it.
As to consistency. I do actually have a job and don’t read everything. That’s also why no one here pays me.
It said “I don’t know why this has been flagged”! Or, at least, the only one I meant to move did.
Some people should be flagged more TBH.
Why? Surely it is possible to have an adult conversation without the need to shut out dissenting opinions. 
Your comment was perfectly logical, but when you’re replying to a deliberate troll, there’s always going to be flags flying high.
You do read this forum…?
I’ll give you that one. 
You aren’t new! You should know this.
Discussions are one thing, the increasingly dramatic “Monzo is dying” users who post day after day to be negative about everything, or to tell us every 5 mins they’ve left. Snore.
Then just merge them all into one thread about it? Many of those users never plan to revisit beyond the initial moan.
