Too many bots - solutions?

Some of the auto leagues I'm in have been in between seasons, sitting idle for a really long time. I know some of the solutions, like inviting other players to join, quitting, or posting on Boards for other managers to join. Are there any others that I'm failing to
recall?

On the topic of unfilled leagues, what do you think about the idea of having a "days since the last game played" tracker* on each open league? Would you be more or less likely to join a league that had been dormant for 5 months compared to 1 month?

*Could be a number in a corner, or maybe green, yellow, or red font

the counter idea would be helpful. it would be nice to have some idea if the league has a chance to start soon. i ended up quitting 2 leagues i was in because they were taking so long to fill and stuck on 4 teams, had 9 teams in limbo, sadly i am not patient enough to keep waiting

@Crackpot I am not sure what the "days since" icon would help indicate? The main solutions are things nobody really loves: deleting leagues, reducing the number of teams, or having people quit leagues they have been in a for a long time and join leagues that are closer to filling up. None of the solutions are ideal.

This is a drastic idea but may get people to join a league: delete any leagues without 8 owners in 30 days and show this countdown when looking at leagues to join. If a league has 6 owners with two days left I expect it would be easier to recruit a couple of owners. If a league only has 4 owners after a month how likely is it it will eventually fill anyway?
