Not to mock you but how long how you played ffl?
That has what to do with the price of tea in China?
From the tone of the initial post, NY18 sounded like he was shocked to see this happen. As if it were the first time. He also said it was a league of friends.
All I can tell you is that the "friends" I play FF with would never do anything like this. (The Ha Ha joke part yes, but not fixing any owners line up for keeps.) I based my response on the cobination of the two. First time it happened, and league of "friends".
Now we hear it's been going on for a few weeks. Nobody else in the league noticed this? Nobody else said anything? Somebody else would have noticed, at some point. Either the guy whose line up was changed, or the guy playing against a line up that was changed. Either way, I would submit to you, that if this league is in fact a league of friends......
It's time to get a new league....and some new friends.
People have done worse in some of the leagues I've been in over the years.
If this was in a league with friends, as it was in NY18s case, then my advice to him may fit for you as well.
