Oh - so all that we have as security for you paying back your loan is "unlimited access" to post bad things about you on social media accounts that we aren't even sure are yours in the first place. That doesn't sound like much security at all.
i dont think instagram is recoverable btw ill show him all my friend list family etc so if i dont pay he can go to them all and trust me seeing my facebook you will realize this is a walk in the park
Yes, it is. Both you and the lender have access to the password, but you have access to your linked email and can easily get a password change right under the lender's nose.
But besides that, posting crap about you on "your" account isn't going to pay back the loan.
Do you have any altcoins? Physical goods and/or valuables? Those count as real collateral.
