when you make your war log public, the information of your past wars is not just available to people scouting the clan, but also to bots that can scrape info on your lineup. The reason I say this is that our clan once had a 32 war winstreak with a public war log. We lost it because some tryhard clan catalogued our previous wars to see who we were taking in our wars and then tried matching up with us on purpose to defeat us. they knew when we started wars as well as who we took with us so they arranged a rosrter that mirrored ours and spun war at the same time.
