Airman Doors, USAF got a note instead of a Warning because he’s been here for a decade, has a great record and your font was pointlessly shoved into the face of everyone who read the thread. I don’t take provocation into consideration when determining whether or not something is out of line, but I do take it into account when I determine the reaction. Contrary to what you claim he was not “given a pass” - Notes are not Warnings, true, but they cut into the amount of slack we’re willing to give posters in the future.
As to your rules lawyering, give it a rest. The Rules are for big deals that will affect people’s posting privileges. This was just janitor work.
Why did I do anything to your post? It ate up 90% of the screen estate on my 10,1" tablet, which broke the formatting and I had to scroll left and right in order to read the thread. When I got home and on to my desktop it was still annoyingly large, so I reduced the font to remove the annoyance for everyone else. Something mods occasionally has to do when someone slips a twenty-paragraph post IN ALL CAPS by the caps-filter or rewrite War & Peace in neon green font. You weren’t dinged for it because I got that you weren’t trying to be a jerk, but the result was still obnoxious and thus got edited down to a reasonable level.
The BB code tools are there for appropriate use. Coloring is a good way to show different authors and edits, like sometimes done in the FAQ. Larger font sizes can be used (sparingly) to good effect in order to direct attention to vital information or create headers where Bolding is used for emphasis or sub-headers. And so on. Using all these tools appropriately is part of what constitutes good manners and common courtesy on this board. Using them as a mere look-at-me is just annoying.
For the record, it looked like this.
