Hi Tabata11,
He is not a scammer he is a busy guy who don't have much time for escrow but still he offers , last time i don't remember the date when i hired him for escrow service he replied me after 1-2 day and after sending funds , when the deal done , he sent me the funds after a day or more .But i say he is not a scammer , you just wait for his reply , he come online multiple times when he was dealing with me but he was not replying to my pm but i m sure that he is reading your all PM's .
Hope for the best.
Unlikely given the whole situation: bunch of people opening trades requests and proposing his as escrow, all with the same approach, being communicative and ready to pay before bet were sent then stopping answering right after.
Bet we'll see.
