The 9 year ban was irrelevant, as Skyyr has continued to fly under various accounts, and fully admitted to circumventing his ban on multiple occasions.
As far as the previous problems reoccurring, if you mean:
Hunting specific players
Coordinating attacks with players on different countries
Using 3rd party comms (Discord) to track other players
Using multiple accounts on different countries to track players (see Ertus, PalCobra)
Crowing on channel 200
Antagonizing other players at every opportunity (his latest squad name was "skyyr 6, shane 1" or something to that effect.
Embellishing and/or flat out lying about the circumstances of his deaths ("good fight you two")
Demanding duels in the DA while referencing obscure events from decades ago
... then yeah, I think that ship has sailed.
Just last night he admitted to being StarFox, Russyn, and Adonai, as well as holding some of those accounts concurrently, and lying about it to avoid them being banned. Then he has the audacity to claim not to be Ertus, and for "proof" says to ask HiTech - the very same HiTech that he completely fooled with his previous accounts.
He never learned his lesson after being permanently banned from Fighter Ace. Nor did he with his 9 year quasi-ban from AH.
A leopard cannot change his spots.
PS. Apologies for propagating the drama in here and on ch200 to those that are disinclined to follow these adventures.
