In case the above posted isn't enough for you to think OP indeed deserves negative feedback, let us have a look at their alts.

OP uses the 1Ju5Q address on several occasions (http://archive.is/vCBJW#95%).


The same address is used by Bitraker, who is a negatively trusted user aswell (http://archive.is/NbBE0#75%).

KingOfBet uses the address 1KCJF to join 777coin (http://archive.is/kf2WQ#10%).


Another address used by KingOfBet is the 1EBxR address (http://archive.is/TPfEX#50%).


The addresses 1Ju5Q used by btcmasterZ / Bitraker and 1KCJF / 1EBxR used by KingOfBets are spent-linked through several transactions:
4bc2af6a31d6eb05ad4cead3763a452fbc09bd6b974432e22e0c9c9499246c9a linking 1CuKV to 1KCJF
ea52b12b1023af768d65b3163086865a3ff0c175bf4e7ca1eb33b43b573c0cfc linking 1CuKV to 1Ju5Q
ca720f91cba21934cd08f3527e8b1c118e98bcc77577728643e3ae0f2e0928b3 linking 1Ju5Q to 1EBxR

Result:
I believe BongOfBet and btcmasterZ to be alts of each other.
