I opened a ticket at Poloniex to get more infomation about the ETC credits issued to users. Here is the reply I received from them:

Hi Stoner19,
The problem here is that one of the tokens did not exist at all before the fork. One could not be a tokenholder of ETH and ETC before the fork, because there were not two tokens to hold; likewise, there were not two tokens to loan out. The second token came into existence at a certain time and was given to whoever possessed the first token at that time. If your ETH was loaned out when the fork occurred, it was not in your possession. You had exchanged it for a debt of ETH plus interest owed to you. The borrower does not owe you anything possession of this ETH may have earned while it was in his or her possession; the borrower owes you only the ETH borrowed plus the agreed upon interest.
Because loaned assets actually change hands, they may not even have been on Poloniex at the time of the fork. Suppose your borrower sells the borrowed ETH to another trader. This other trader uses their own BTC to buy it in the spot market. They then withdraw it to their own wallet. The fork occurs, and the trader now has ETH and ETC in their own wallet. Neither the lender, the borrower, nor Poloniex has any control over or right to this ETC. The trader is fully entitled to it.
What you are saying is that the hard fork, which occurred outside the borrower's control, should somehow have added to that borrower's debt. Those were not the terms of the loan.
Best regards,

The next question I've asked them is in regards to the lack of notice given to users. I most certainly would have stopped my lending scripts and turned off the "auto-renew" function for loans in hopes of at least getting some of the ETH back into my account prior to the hard fork.
I very well may be beating a dead horse at this point and maybe I am the one in the wrong, but I still don't feel like this whole process was handled properly nor professionally.
