This happens late in recruiting when a player who hasn't seen any effort at all from any teams decides he wants to reach out to local or regional teams in hopes of getting a scholarship. He will show up as considering any team he reaches out to, which is sometimes as many as five teams at once.
As a result, if you click on the guy who just sent you that message about himself, it will look like your school and several others are in a heated battle over this previously untouchable recruit, when in fact none of you ever went after him to begin with.
Also, he will show up on your team's considering list in profile, which is perhaps the more annoying part. If you're still active in recruiting players you DO want, now people suddenly see an extra guy there and think you are spending in more places or are going after more guys than you have openings for, and it can lead to potential battles you don't want because of misinformation (and, really, the other guy really shouldn't want this battle either since you really AREN'T spending what he thinks you are and he's initiated a battle based on that same misinformation).
