First of all, this whole FB Goat thing is just something you proclaim yourself as, it adds nothing to why a spot should be reserved for you.
As for you creating this league, yes this is true, but like in real life, if a company founder does something wrong and gets ousted by the board of directors - do you think he can just come back few years later and say "sup homies, coming back to reclaim my company since I created it"? That's not how it works son.
You are right that no returning members have ever had to apply for a spot without finishing bottom 4 - but that's because there's never been a member that finished top 10 who left the league afterwards (aside from Tian, but he didn't say he wanted to return) to begin with
Even though Tian made the playoffs in his last year with us, he'd have to be voted back in as well had he expressed desire to play again, there's no reserved spot for him. Don't see why there would be an exception for you.
Secondly, the reason you got kicked out of this league in the first place, as Stat said, was because you pulled shady sh1t before. So whatever misconception that you had that a returning member could get back his spot anytime does not even matter anyway.
That said, I don't want to get into meaningless arguments that would just waste both of our time - I'm not the one that decides who gets in/out of the league, all the members decide on that, which is why there is a voting process in the first place. If the majority wants you in, then you'll get in, simple as that.
So, go ahead and apply, post a screenshot of your entire fantasy record history, with such a prolific profile I'm sure it won't be a problem
