No, not usually.
It generally depends on the situation on what happens. Obvious inappropriate language is almost always going to be penalized, even if it was deleted/edited. If it was active long enough to be reported, that means folks saw it, and therefore moderated according to the content.
Other behaviors can be a bit more nebulous. Trolling, or otherwise being sassy, may not result in a penalty. We have some fairly strong personalities around, and while some of the tone used doesn’t always seem productive, a lot of the resulting discussion from that is almost with the same tone. In a situation where there are fairly aggressive and reactionary posts all around, that may limit the actions that are taken.
Edit: Just to note, there are a lot of accusations and derailments flying around from a fair number of people. I’m not going to point fingers, but it seems that the attacks and accusations aren’t limited to a single person.
I’m going to clean that one up and remove a bit of the back and forth, if not just lock the thread.
