You do not have to insert them individually. Go to that page, highlight all the lists on that page, copy to the clipboard, then paste them in to the adlists in Group Management and save. As long as there are no dublicate lists already in the database, they will all import.
Then rebuild gravity, either from the command line or the web GUI.
If all you want to use are the the lists on the referenced page, then run this command from the Pi terminal first, which will clear out all your existing lists. Then when you paste the new lists, there will be no duplicates.
sudo sqlite3 /etc/pihole/gravity.db "DELETE FROM adlist;"
Diese praktische Funktion viele Listen gleichzeitig per copy/paste in die Zeile einzugeben funktionierte bei v4 bei mir immer problemlos.
Es geht auch mit v5, allerdings stark abhängig von der Formatierung der Listen und des verwendeten Editors. Irgendwie zickt es da etwas rum.
Einfach mehrmals probieren, klappt dann schon...
Why are you chasing a big count on your blocklists? If you aren't seeing ads now, adding more blocklists typically just causes more problems that you have to whitelist, and no more ads will be blocked.
