FYI: (streams) filter documentation
In case anyone's interested, (streams) has some built-in documentation for its filters now which still work similar to Hubzilla's. For example here:
https://fediversity.site/help/guide/en/Content_Filters.
By the way, (streams)' N.S.F.W. has been reworked, too. It uses HTML rather than JavaScript now, and it appears to use the same syntax as the other filters now. So the above documentation is valid for N.S.F.W. as well.
Hubzilla's N.S.F.W. at least supports regular expressions AFAIK.
