Oromagi would intentionally accept multiple debates from users he knew were going to get banned or were so spread-out he figured they'd miss rounds or post shallow crap just to spam wins.
Ramshutu spearheaded me being punished for the same thing, the only difference being that because I am so intelligent and observant, it was proven I knew this user would get banned with more assurance than Oromagi could be proven in his scenarios.
I have had multiple, at least 12, debates robbed directly from me that would have resulted in an elo-gain because of my honesty to the mod team about users. Many banned users got banned because of reports I myself made in the first place.
I even had debates that I made and the banned user accepted, deleted.
I say at least 12 because it was 12 if I recall correctly, yet due to that I became phobic of accepting new users' debates as I didn't want to waste effort on what would get deleted.
I wouldn't blame this phobia on 'holding me back' it's actually proven quite wise indeed as I study my opponents more when debating and structure things to make it awkward for their particular style of debating (or at least I try to) which I can't really do with a new user (or returning banned user who appears new).
As for this scenario, Oromagi has even personally refused this but he has had the fortune of his opponents barely ever actually asking for mercy.
On the other hand, David, Ramshutu and plenty of other high-rankers are provably assholes to opponents who beg for mercy based on time/effort constraints or who entered a debate on the wrong side because of a 'instigator is Con' trap or something along those lines.
The truth is I have indeed agreed to delete debates entirely, not just tie them, in this scenario with 2 specific people before if I recall correctly. I show respect to respectful opponents. If my opponent is a complete and utter prick, I neither show nor ever request mercy from them in this scenario either way around.
