The policy may change in the future, but for now I simply don't have the patience for people that either don't read my blog and randomly show up to comment on random threads or, for whatever reason, feel like being comment-trolls. Have fun wasting time in someone else's comments section.
P.S.: For those that have strong opinions about this and really want me to change it back, feel free to email me. Maybe I'm just overreacting.
