I must change url to filters.

Old url https://www.certyficate.it/adblock/adblock.txt
new url https://raw.githubusercontent.com/MajkiIT/polish-ads-filter/master/polish-adblock-filters/adblock.txt

I make redirect from old to new url.

Thanks
