Unless Theymos changed their mind this is how he thinks about a similar situation:
I think that marcotheminer should return the account now since it was probably hacked, but everyone should give yussuf89 negative feedback for being unable to stand behind his account's actions unless he pays 50-75% of the loan principle. (This is just my opinion -- I'm not going to try to enforce it.)
Not the "I'm not going to try to enforce it" part. You really do have to work it out with Altcoin4Life. And that (usually) means compromise.
Also for future reference these are the password changes on the account:
January 14, 2016, 10:43:08 PM - murderouskirk - password changed
January 13, 2016, 11:59:41 PM - murderouskirk - password changed
January 13, 2016, 11:18:51 PM - murderouskirk - password changed
January 13, 2016, 11:15:09 PM - murderouskirk - password changed

On a side note: is there any evidence that the account was hacked? Or are we to believe you on your word?
