Hi Scott,
I hear your analogy and don’t disagree. In fact, I fully understand what you are saying.
In this particular example, I can tell you that there were a myriad of posts (off topic) relating to remote controls. I would at a guess suggest about 20. (Please mods don’t go and split up the thread now). However, in my belief, they all added something to the discussion despite not being directly on topic. The topic itself was well received with many users adding their thoughts.
Notwithstanding as per Ged’s comments below
The off comment ‘flags’ referred to specifically here were a mere line or two, all in good spirits and really didn’t detract from the thread.
I had replied something to the effect that I was a tennis coach for many years and am missing staying up late watching close matches at Wimbledon to all hours of the morning.
On topic? No Harmless? Yes
And my thought relating to the ‘humanity’ of the forum still stand. Would I make a special thread/announcement: Hey guys, I was a tennis coach for many years? Of course not. However, as a tennis pun was mentioned I took the opportunity to reply, which in turn let people know more about me. I’m not just a faceless individual and Roon user.
Over and above all of that, I still get it was off topic & moderators have to make a call what to edit, delete, move and so on. As per my comments in this area, I’m hardly upset or angry or even anything untoward. Far from it…I get it. 
As for me personally, I don’t think you’ll ever find me flaming, using bad language etc. That’s not who I am here, or in the outside world.
Where I did see the need for moderation, as per my first reply above, was quickly moderated & the OP rectified the situation via PM. Sure, I could have simply ignored the post, however directed at me, I felt the need to reply in an assertive (not rude) manner. I’m sure that will be a one off situation (or outlier) in so far as I’m concerned.
Just to reiterate…of course, the forum needs moderation!
Of course, I understand it’s a thankless and awkward task!
And I respect the fact they are doing their best to have this Roon forum the best it can possibly be.
What I will say is that people do write in different styles. We aren’t all from English speaking countries, so often mods really have to read between the lines to make a call. Over and above that, even when people are from English speaking countries they do not necessarily write clearly or try to be humorous which is totally lost in written form and so on…It’s difficult.
Have fun all & just enjoy the music.
