I'm not sure how involved you were at the time, but there were plenty of people simply saying positive things about him, no worse than like "Luigi Rocks!" and getting their comments removed for it. You may have had a more understandable policy for how you enforced it, but the rule was made for silly reasons. The thing is, that rule was made for the purpose of removing posts and banning repeat offenders that held him up as a person who had done a good thing. But he is a person who did a good thing.
thirst-posting him while saying he's both innocent and being used as a scapegoat, I would say is free game.
Thirst posting is always removed, as it should be. But one of the mods, former now, who was also enforcing the anti-lionization rule was doing so because they believed, still do apparently, that he was innocent and being used as a scapegoat.
), yet you don't even know what the words you're using mean. Example: "it exudes some very poor ideologies" 
I'm not too concerned about what I can and can't say now regarding Luigi Mangione. I think we all at this point wouldn't bat an eye at anyone "lionizing" him as described in the rule announcement post. But I'd be lying if I said it doesn't still grate on me every time I'm reminded of it and that it technically is still a rule.
I don't mean to stir months old shit, but I still bring it up because I don't feel like it was ever rectified. Like one of those things all the involved (users and mods and admins) just tiptoed away from after it became more and more apparent how bad of a rule it was and how messed up some of the mod actions were around it (see below). It was a problem that never got addressed, and the rule is to my understanding technically still in place. I'll put a spoiler tag on the rest to make it easy to ignore for anyone who doesn't care and to not further derail OP's discussion of fedposting. But it still is important in my opinion to acknowledge what went down, and it does have actual relevance here where we're talking about potentially new rules on what constitutes fedposting.

You said it was news to you that it was still a rule, but it is still a rule, isn't it? Just not one that gets enforced anymore.
The rule announcement, that I linked to in a previous comment, was made by an admin of the site, not just a moderator. I think it's safe to say it even became something of a struggle session. She may have mostly forgotten it at this point, I don't know, but I think @Awoo@hexbear.net would attest to it. Below is the text that still sits as just a Removed by Mod comment with 92 upvotes that you see a couple comments down if you follow the rule announcement I linked above. (92 upvotes on a removed comment. I wonder what the record holder is on Hexbear for upvotes on a removed comment, I would bet that one's in the running.)
If that's too hard to read and opening it up in a new tab doesn't work, you can see it here https://hexbear.net/modlog?page=1&actionType=All&userId=430 since it's not like Awoo has much in the modlog. (The supposed DM harassment also turned out to be a bogus excuse). I'm assuming you don't mind me pointing this out and tagging you, Awoo. I'll delete it in a second if you want me to.
I just really hate it when this sort of thing comes up around what is considered permissible speech here and the whole Luigi lionization episode slash struggle session is pushed aside or memory holed. Especially when that rule, as far as I am aware, still stands.
