2 years is a lot of time and I'm only coming to the Knowledge of your case just now. I think your bim of hope came out of the recent case of Pokapoka124 that just got unban but you ought to know better. When it's blatant plagiarism that counts into at least 50% of your post, it's of no use being unbanned.
You've been around more than I have and I must say, even an account created for the purpose of appealing a ban is supposed to stay the course of an appeal and not participate in any other activity of the forum including posting on other threads but, your user could be said to have violated that rule. In essence, it could be seen as ban evasion which in turn, puts out your appealing account for a ban.
I feel for you, looking out for possibilities, signature bans and even paid options to uplift ban but, its kind of difficult to open that window isn't it. In one instance, it could lead to some sentiments that would bring in corrupt practices of paying to lift ban and sentiments or having users banned just for any case with eyes fixed on payments to uplift the ban.
I suppose you should have stayed the course of an appeal and hope for the best but, you didn't really, did you!
