OK. Here it is.
Note that it is a long term user, a well known rule and the mods did give a note on it - it violated the rules. What is the justification for the poster getting a pass? And unless there is a mod rule in place like 3 mod notes = 1 warning then yes, you gave the poster a pass for (again IMO) a poster intentionally violating the rules.
The question remains: why not a warning? What’s to stop that poster (or any other) to do this again and again and again?
