yeah, but people can change email addys and reregister...  
 
commissioners do need power to fix situations, nothing says a commissioner cannot report an owner at the same time, just that they are able to alleviate the problem at that moment as well.  
 
to try to explain in words and hope fleaflicker handles it all the while the cheating or whatever is still in place is kind of crazy.  
 
allow commissioners to fix problems all the while both commish and owners can report abuse as a flag.

We have a system to report owners. From the FAQ:  
 
What about bad owners that cheat?  
 
If you suspect an owner of unfair play, you can report them by clicking Report Abusive Owner from the Owner Options sub-tab of your team page.  
 
 
Ultimately, these reports will contribute to an overall user rating like you suggested so abusive users will be flagged for life (similar to the concept of buyer/seller ratings on eBay).

well I agree there should be a system in place to report abusive commissioners, like maybe some kind of rating system (yes, just like ebay)  
 
Now with that said, commissioner does need more power such as that to be able to adjust any team's roster, reverse trades, reject trades, reverse and forbid drops from team, etc...  
 
for every bad commissioner, I would guess you would have several bad owners. I say that because all it takes is two owners to do some kind of collusion and it harms the entire league, and this does happen. A couple of instances might be if a guy signs up for 2 or more teams using different email addresses and then drops players from one team to help his other team; or if a team realizes he is not gonna win the league, he trades great player for a few ok/good ones; drops a player knowing the bottom guy will pick him up; etc...  
 
It does happen. The logic behind giving a commissioner much needed powers to adjust rosters, reverse trades, etc.. is to keep the league in check. If an owner goes astray and tries to get away with something, the commissioner can fix it and verbally correct the owner's thinking and all may be good, but if all the commissioner is able to do is kick player out, then that may be a bit harsh.  
 
Generally, a commissioner is one who started the league and you need one person to oversee all teams otherwise it would be chaos if the league could not be fixed.  
 
ideal fix would be to have some kind of rating system for commissioners, both good & bad;  
give commissioner much needed ability to correct small problems with trades, player dumping, etc...  
 
they would work to keep the whole season running smooth.  
I have been both team manager, and commish.

yes that sounds like a good Idea this way we see who the good and bad are.

I like that idea Steve it would help both sides that way it would help keep good leagues from being ruined by "Idiots".

An ebay style feedback system...both sides get to post opinions of owners and commissioners, good or bad. That would do lots to help develop reputable leagues in the future.

I have seen commish on other sites who kick people out for no good reason and even lie to justify it a reporting system would be a good Idea.
