text: should advertising your fantasy sports league in the main fantasy sports message boards be considered spam? more than half of the posts that i see on fantasy sports message boards are from people trying to recruit managers to join their private leagues.  typically they'll give a brief description, possibly the league settings, then they provide the league id and password.  i've done the same myself when i needed to fill a league.  my league advertisements are written in good taste and seem effective.    but recently i noticed that i've been locked out of posting on all of yahoo!'s fantasy sports message boards.  presumably i've committed a tos violation but i can't think of anything i've done that could be considered a violation, unless it's these sort of league advertisements.  are these league advertisements spam?  is that why i was locked out? absolutely!  that posting is no different than any other 'unsolicited commercial offer' posted in any other group or sent via email.  it's always bothered me that people do that and now i know why.
