He/she sent me a PM stating that this was a mistake (wrong person), so this issue is resolved

Again, posting for transparency and in reply to KidRocks.

These are the 3 PM's in my inbox from KidRocks
[1] https://gyazo.com/1639f98c274d171586fcdf3e3a60e29c
[2] https://gyazo.com/5f5e2a48292a5164087128092b590945

There are a number of inconsistencies with his claim and I am seeking further explanation before paying out to him/her. My reasoning is explained below.

1) The transaction seems to be MasonIII giving $110 skrill for KidRock's $100 BTC.
2) The 2nd PM indicates that he or she wanted me to send first rather than the other way around
3) KidRocks is now claiming that he or she sent me $30 BTC.

Points (1) and (3) are inconsistent since the original transaction was for $100 BTC, the number of $30 appears from no where.
From point (2) there does not seem to be a transaction or any understanding of a trade occurring so I do not understand why a payment would have been made.
The address quoted in the second PM [2] does not have any incoming transaction for the amount of $30. (Illustrated below).

Given the negative trust on KidRocks account & based on the evidence I currently have (which if anyone has arguments for or against, I would love to hear), I am inclined to believe that this is a scam or attempt to place a claim in order to take advantage of the situation. Therefore I am currently deciding to NOT pay out the $30 claimed. If anyone, whether involved or not, has issues with my logic or additional evidence or a correction on my understanding of the situation, please do chime in and correct me.

Regards,

Mason
