Please post network statistics or something to show a spike in network activity / lags coming from this app.
I also noticed some oddities yesterday running DemonBuddy+PokeFarmer, but there were a number of other elements at play, so unless it happens consistently, I'm not ready to point the finger at the Buddy servers yet.
For what it's worth, I hear of people running multiple HonorBuddy and DemonBuddy sessions all at once and not having lag issues with the bot engines.
