One other thing.
If you want to accuse FD of being "Liars", do you actually have the evidence to back it up?
Do you have links to posts or documents from FD, or emails from support or suchlike, that clearly say:
1) "We review all videos submitted with all reports and tickets / We always watch every video submitted in any ticket."
2) "We have reviewed this video."
3) "We conduct a fully detailed review of every single combat logging report and write a detailed 30 page report about it (slightly sarcastic but you get my point)."
Before you accuse them of being liars, you should present the evidence of the actual lie that they made.
Without that, it seems to me that the accusation is based on your assumption of what you think FD should be doing, rather than actual proof of a lie. As has been pointed out by me and several others, I suspect they don't pay any attention to a single report of combat logging by any particular player, regardless of the level of proof provided.
You would be better off by presenting real world evidence, supported by videos, of the same player combat logging many many times over a sustained period of time, combined with all the reports and ticket numbers that you submitted. Obviously you would have to do that on another location since that would be naming and shaming here on these forums. This would demonstrate that they are not linking the reports against the same player together in any way.
Once again, I am against combat logging and I think it's totally stupid - I mean if you are going to combat log, why play in open in the first place? But, it's very difficult to prove in a P2P game architecture.
I would also like to hazard that if you ban a combat logging player, they are probably just going to stop playing, or play in a private group or solo from then on, so either way, you probably won't get to attack them again.
