It wasn’t before: we’d always get told that just “disagreeing” with someone wasn’t enough to merit a warning/suspension/banning, no matter how odious their tactics and rhetoric were, with the implication that the troll in question would get a free ride because mods weren’t mind readers. [I then got a warning when I tried to point this out, undelicately admittedly] This changed when we got a brand new batch of mods c. 2020-2021.
Which of course involved “reframing” (strawmanning) the poster’s [@Euphonious_Polemic’s] concern by the (former) mod in question, after someone got warned for calling out a troll’s tactics in a non-Pit thread.
Note I am glad for said sea-change, as mods mollycoddled these people for far too long. Haven’t seen the above kind of dismissal by any mod in a number of years now, and very few “instigator” warnings of the above sort.
