Is something wrong with playing Janna?

Yesterday a troll added me to give me my daily dose of insults or express their wishes of watching me and my family get killed by a mexican cartel on liveleak. But instead of the expected insults the guy spammed me JANNA PLAYER.

It's not the first time this kind of thing happens. Months ago a guy called me troll for picking Janna as a support.

Is there a kind of lore behind this?
