If it is indeed true that you are in fact multiple people and have independently submitted articles relating to your (actually pretty cool sounding) event, may I suggest that you coordinate in the future to keep the articles submitted to just a few at a time, and make your comments more substantial.
This would probably stop the accusations of you running an Astroturf campaign.
Although this particular form of astroturf probably has better inside jokes.
