Judging by the posts, the account has been sold. After 3 months of silence, the author began to be active, but the posts are already written in Russian.
It doesn't matter if it's been sold or not, as long as you've provided evidences to back your claim that you're the original owner of the account,then the only issue now would be time, I've been on the forum for quite some time and such issues take time before they get rectified(thats if they ever get rectified)
I do hope you get your account back soon
