Password Protect League

We have a lot of false accounts joining our league if we password protect do managers have to contact the host to join ?.

If you are the only person who knows the password then yes, otherwise they could just as easily ask anyone else in the league for the password. I believe players already inside the league don't have to input a password even if you introduce one so I guess the latter is irrelevant in this case

Thanks 360. What I am trying to do is make managers contact me and then I can look at their history and make a decision on letting them join the league this might sound extreme but I am tired of kicking false managers (other league host's) who I believe only join to make the league uncompetitive. 

hope a mod/dev helps you soon then, maybe screenshots of who you think the fake managers are might make it easier for them to help

Imo, password protected leagues are not inviting at all.... First and foremost, there's no way way to get the password to look at the said league because there's no way to contact the host through a filter search.
