Yes, there is a method actually. All you have to do is add a random GTA clip on the second half of the clip. This method is enough to fool the Instagram video reel duplicate detector and it even works with YouTube shorts.
where could I get this botYou could use the reposting feature from some bot that automatically does something like this thing, mentioned by @ristoriel , (though on a visually unnoticeable scale).
I personally haven't seen any bot in the market that is capable of doing this (which includes Jarvee and Massplanner). Except for NecroMancer.
