Where to get good free backup M3u Playlists?

I just watched the Lomachenko fight on a free sports m3u lists after my iptv provider didn't bother to create ch for the fight. I did a paid trial for 36hrs with a new service none of the ch work well and their espn plus is all errors. I experienced one minor Hickup with the freebee m3u but the fight steamed 720p. I heard old timers preaching iptv is the a scam you can get the links for free so I'm interested in seeing what's out there without redbox type apps just looking for sources because when I use to use kody none of the links loaded well if at all so I'm wondering if Like would be beneficial for live streams... Any input and insights are greatly appreciated
