So do you consider positive comments that get positive engagement to be a benefit to your community? If not, I get it, and your position is basically "I just don't like throwaways regardless of their contribution". But if that's not your position, you don't seem to have much of an argument yourself. Also, there is no "freeriding" if the throwaways are actively producing positive content. You might as well call every single user a "freerider" - what are they contributing at all? Is your forum getting paid by someone based on an estimate of "real users" or something, and throwaways screw up your numbers? It really doesn't make sense. The idea that a static username alone has an outsized positive effect on your community doesn't seem to be provable, in the face of accounts like mine. Maybe you're just making a general rule so you can eliminate the majority of accounts used for flaming or spam, I can't tell.
