kirbyMy team was scrimming a team using bape as a ringer. Bape early in the game rage quit and started ddosing their sub and the team's mumble. Bape also plays/played sort of frequently in tf2mix.
I know this might be a long shot, but he could possibly be the who ddosed/is ddosing atf2 (possibly knowing that it would mess up tf2mix). I could be completely wrong, but whatever.
I'm glad you caught onto his ploy. Would never have expected the guy giving a decent alternative in the meantime was the one doing it.
