The reason I suggest making it filter-in is because it seems to me that it’s easier to make a meaningful filter that accurately detects a lot of sensitive stuff than a filter that accurately detects spam, because “spam” is kind of open-ended. Or I guess in practice spam tends to be porn bots and crypto scams? (Even on LessWrong?!) But e.g. truly sensitive talk seems disproportionately likely to involve cryptography and/or sexuality, so trying to filter for porn bots and crypto scams seems relatively likely to have reveal sensitive stuff.
The filter-in vs filter-out in my proposal is not so much about the degree of visibility. Like you could guard my filter-out proposal with the other filter-in proposals, like to only show metadata and only inspect suspected spammers, rather than making it available for everyone.
