I doubt if they read these threads, but if you want them to clean out some leagues, I recommend sending email to support:
365support@strat-o-matic.comThey're typically pretty responsive when I inquire. Some months back, I send them a spreadsheet of all leagues with 0 or 1 team and asked them to delete the leagues (and for the leagues with one team, just pull the team out of the league). They deleted all the leagues with 0 teams, but left the ones with one team in them. Kinda stupid -
some of those leagues have been on the page for literally years!
