Did you add replay protection
No idea what that is or if I did

Replay protection stops other Forkcoins to transfer to the same address. BCH/BSV/BCH-A by default don't use replay protection.
The Poloniex address is 13jaEByoEb78iMAVM7QsJosxxwZbt3hr9k
Blockchair shows only BCH has moved. Your
sending address had received the transaction on the same day (I guess you sent that within your own wallet), and
those funds were received in 2014. This address
still holds BCH-A and
BSV. If you have a significant amount, you can claim BSV/BCD/BTG/BCH-A too. If it's only a few bucks worth of BCH, the others lower than BSV may not be worth your time.
