This post was flagged by a user who doesn't think we are banning that particular word (damn). I don't think the flagger really intended us to remove the post, but rather to encourage me to respond to it, which I am now doing.
When I wrote the quoted policy, we had a bunch of really young users on the forum, some of whom objected strongly to even the mildest of swears, and since swearing is rarely actually necessary, I was willing to accommodate them. My personal opinion is that people shouldn't be afraid of words, not even That Word, and it bothers me a lot that people are no longer encouraged to read Huckleberry Finn, the Great American Novel, in which racist characters are depicted using the language of racists.
In the current case, the OP responded to @sathvikrias by removing the word in question from their post, I guess agreeing that it wasn't necessary to what they were trying to say. So this specific case is moot. But I would not be inclined to censor the post in its initial form, which I consider a vanishingly mild case of swearing.
Aside from mildness, in this particular example, the poster was using the word in question to express frustration with themself, not to attack someone else, and I'm especially inclined to allow that. Name-calling against another user is a kind of bullying, and I would happily censor that, even if the word in question isn't on anyone's list of banned words. Take for example the word "evil"; if you publish a game project in which the player is fighting the forces of evil, I think that's fine, but if you call another Snap! user evil, you'd have to be responding to something that really is evil before it'd be appropriate--torturing animals IRL, say, but not torturing animals in a game.
I'm sorry I'm not laying down a simple rule that would be easy to follow, but sometimes people use strong language in response to something that really provokes it, and I've been known to use such language myself in such situations.
P.S. This is just me talking; I've tried and failed to get my colleagues in this enterprise to spend some time working on forum policy issues. :~( They'd rather spend time on actually improving Snap!, as would I!
