You need a little Python knowledge to write your own fitlers, but python code is very good at being readable.

Header filter:

Code:

class PrintReferer(HeaderFilter):
    "Print Referrer if it differs from the request domain"
    name = "Print Referrer"
    In = False
    Out = True

    @classmethod
    def action(cls, req):
        domain = re.match(r"(?:.*?\.)?([^.]+\.[^.]+)$", req.headers['Host']).group(1)
        referer = req.headers['referer']
        if referer:
            referer_host = referer.split('//')[1].split('/', maxsplit=1)[0]
            if not referer_host.endswith(domain):
                logger.info('Referer: %s', referer)

Web page filter:

Code:

class NoIframeJS(PageFilter):
    name = "Remove All JS and Iframe"
    active = True
    urls = ('.badsite.org',
           'andyou.net/.*\.jpe?g',
           'gotyou.com/viewer\.php.*\.jpe?g')
    regex_subs = ((br'(?si)<(script|iframe)\s+.*?</\1>', br'<!-- \1 removed by FILTER: no-js-iframe -->'),
                  )

regex_subs is for regex find replace. string_subs is for string find replace.
