Right, I've done some investigating and here's what I've found:
On the evening of the 12th September, Gabyral and Dogbite found that the TPF forums were about to have the server wiped clean and that the payment renewal was set to expire. Both were due to happen at midnight on the 12th. Gabyral and Dogbite were able to prevent both these events in the nick of time (think Goldfinger-esque prevention in the last second). Gabyral assumed KD was responsible for this as very few people have access to these settings and KD was leaving.
Discussion of the facts with the involved parties (KD, dogbite, gaby) has led me to the following facts:
1 - There is no evidence to suggest KD has commited any wrongdoings
2 - There is significant evidence that KD did not have any internet access between the 11th and 13th of September
3 - KD had been trying to peacefully retire from TE in the days before he quit.
4 - The server wipe and payment renewal failure are probably linked
5 - The payment renewal failure could be caused by the company Dogbite is paying.
Finally, this leads me to the conclusion that KD is innocent.
However, this does lead me to three suggestions:
1 - Gabyral owes KD an appology for accusing him of trying to destroy the TPF forums
2 - KD owes Gabyral an appology for making this all public
3 - Tiberius and thewolf owe KD an appology for attacking him over this
4 - It's time this incident was put to rest.
