@LogitechMouse, I also think you should create a type 3 flag for this user. He's demonstrated some pretty scammy behavior: He tried to borrow from shasan using two accounts, posting requests within 25 minutes of each other. Then, after being called out and having his alt linked to this attempted scam he got busy deleting all his loan requests. I can only assume he's trying to hide evidence of his shady actions.
@lighpulsar has created a flag against him already and I will just support it. My mistake that I didn't created the flag first because I'm still hoping that he will pay the loan but because of what you have posted that he tried to borrow from shasan using his 2 accounts, I've decided to just support the flag since a flag has been created already and I'm not hoping right now that it will be paid.
Anyway, its my loss and my I've learned from it too but if he will pay anytime soon it will be good for me and for him too if his account is important to him. Thanks for your help

and for everyone who shared information here

.
Well the flag that i've created is only a type 1 flag it only suits for users with shady behavior or atleast tend to scam anyone. although this case where btc is involved and the contract or agreement between the 2 parties was broken this where the type 3 flag came in but only the creator of the agreement or contract (which is you, logitechmouse) against the user who broke the contract (daboy_lyle) with enough support with DT members daboy_lyle will trust turn red and "warning trade with caution!!!"
This is why i urge you to create a type 3 flag against daboy_lyle since that is the flag suits for this case. it's not too late create that flag since it will create red trust. I can withdraw my flag against him since it was only a type 1 flag.
