Re: Question about reported post....
Yes, I've read the unpleasant exchanges in non-tennis theorising about why the thread was locked.
The thread was closed because the fighting between several posters had derailed it off topic - though the topic itself was certainly an invitation for conflict in itself and may well have eventually been closed anyway.
That specific post itself would not have led to thread closure - if complaints alone had been received about it, it would certainly have been a candidate for removal given its potentially inflammatory nature.
Unfortunately, by the time that the thread had been drawn to the attention of the administration, posters had taken matters into their own hands and the fighting had already started so there were fewer options.
Regarding that specific post and its acceptability it is a difficult question for me to answer. It was open to interpretation which makes it difficult to act on or speculate on the motives behind it without some more tangible evidence. As I said, it certainly would have been considered for deletion if clear reasons were provided when it was reported but if no one had complained about it, it may well have been left to just fade away.
What I would add is that once the fighting starts, it's hard to single out individuals as blameless. Which leads to the options of acting against all or none of the posters involved if action is indicated. Which is one of the reasons why we encourage posters to use their ignore lists and reports posts rather than get into repeated fights.
I hope this answers all your above questions.
