@mastohost @strizhechenko maybe something like this could work. but peers lists are not updated instantly and 10 is an abstract number. for servers with thousands of peers this may be not good solution. maybe the percentage could be used: nonexisting domains to total records number. something of the kind. I will try some when I have more spare time. I have to do my work. PHP is definitely not my work, although I added some extra checks to avoid extra load on exploring and/or processing of the blocked or nonexistent domains.
