Argument - Before casting this vote I checked the voting policy on Full Forfeiture.
"Should either side forfeit every round or every round after their initial arguments (waiving is not an argument), the debate is considered a Full Forfeiture, and any majority votes against the absent side are not moderated (a vote may still be cast in their favor of the absentee, but is eligible for moderation to verify that it is justified via the normal voting standards).". https://info.debateart.com/terms-of-service/voting-policy
It seems that even though Pro did submit a very limited round 1 argument, Pro was still guilty of full forfeiture by forfeiting every round there after.
However, Con did not even present a round 1 argument, and did not rebut what little was written.
In any other debate what little was written would probably have resulted in a foregone conclusion for the Con side. But given that "Lily was the most talkative....at first...." defeated anything that Con did not reply to, I guess that seals it.
And the voting policy does stipulate that a vote can be cast even in the event of what would otherwise be a full forfeiture - Pro
Sources - Tie
S&G - Tie
Conduct - Pros conduct was marginally better, at least posting one round 1 argument. Perhaps had it been responded to we would have further correspondence from Pro - Pro
Perhaps you should try to start out something as subjective as this with a framework, it would be very helpful in establishing and actually substantiating your resolution.
Good luck on the debate!
