Did you set up a pattern of behaviour using your alt accounts to establish a clear history of combat logging (via taskkill)? By that I mean did you simply record a handful of videos and submit a handful of reports (eg 1 or 2 videos/reports per alt), or did you additionally establish a pattern of combat logging behaviour on those alts over and above simply the video evidence? My point being is that Frontier's own investigations, as I understand them, will examine the behaviour of that alt over time, not simply the recorded occurrences, and I suggest likely don't need to include review of video evidence anyway, if their own datalogs provide the pattern of behaviour evidence required for a ban. If you don't have a repeated pattern of behaviour on those alts of combat logging by taskkill in combat over a period of time, Frontier may not feel action is required. I don't think the OP clarifies whether the alts have the necessary pattern of behaviour beyond the video evidence submitted.
