The leagues i played in , rules were put in so owners cant start players on bye weeks or listed as IR or OUT .
for players that were listed were OUT , they had to be on the Wednesday's injury report for Thursdays games and Fridays injury report for weekend games so not to penalize owners if a player got changed at the last minute as not every owner is 24/7 or follows it every day .
The penalties start off with a warning , then fines , if an owner gets 3 illegal lineups in the regular season they can be removed
the leagues that i was the commissioner , i didn't email or post when i saw illegal lineups as every owner knew the rules and their responsibilities and i didn't want to make extra work for myself and didn't want any owner to accuse of me bias if i missed a violation and didn't give a warning
if an owner wanted to do this every week on their on time , i would've appreciated as a commissioner and as an owner i would be o with it as long as they stick to bye week or players listed as IR or OUT and not give lineup suggestions
