Every social media platform is peculiar for specific reasons and various sellers, so depending on what you're pitching and since Reddit did work out once why don't you rinse repeat fix whatever got you banned.
You learn from the mistakes not disappear all together, don't know how long you've been successful or using reddit but not a good idea to throw all that away and start afresh on another platform.
Roll your sleeves up and dig in again, and again, if you get banned 100 times try 101 at least you've learned (or I hope) 100 things to avoid from getting banned on reddit.
Also read a lot on this forum people share experiences especially Reddit.
So give it another try, all the best...
